The behaviour of Type-1 & Type-2 cores related to provision of checksum increases the packet length for Type-1 cores by 2, as the checksum is appended at the end of data packet and the same is made accountable in the DMA status. The STMMAC cores beyond Version-3.5 provide HW interface registers which allows the user to read the HW capabilities, while to support the previous cores the information related to HW capabilities has to be provided from the platform code. The Type-1 cores which do not have the HW register interface need this information. This patch also updates the driver's doc.

The platform specific code will provide the default value of this scaling factor, based on the input CSR clock. There is an option to set MDC clock higher than the IEEE 802.3 specified frequency limit of 2.5 MHz. This applies for the interfacing chips that support higher MDC clocks. The resultant higher clock of 12.5 MHz requires additional Macros to be defined for the clock divider corresponding to the to the following selection. ----------------------------------------- Selection MDC Clock ----------------------------------------- 1000 clk_csr_i/4 1001 clk_csr_i/6 1010 clk_csr_i/8 1011 clk_csr_i/10 1100 clk_csr_i/12 1101 clk_csr_i/14 1110 clk_csr_i/16 1111 clk_csr_i/18 This support has to be added both in the include file, as well as driver. The driver need to program the registers based on the interfacing chips. This would be more board specific information and needs to be passed through the platform code to the driver.

The previous work didn't add the other fields that can be used to achieve MDC clock of frequency higher than the IEEE 802.3 specified frequency limit of 2.5 MHz and program a clock divider of lower value.

This resolves two issues with untagged traffic: 1. untagged traffic has no UP in packet which is needed for QoS. The change above allows setting the schedule queue (and by that the UP) of such a stream. 2. BlueFlame uses the same field used by vlan tag. So forcing UP from QPC allows using BF for untagged but prioritized traffic. In old firmware that force UP is not supported, untagged traffic will not subject to QoS. Because UP is set by QP, need to always have a tx ring per UP, even if pfcrx module paramter is false. Signed-off-by: Amir Vadai Signed-off-by: David S.

The framework is implemented via an ops table which defines the following functions: rx_bcn_presp() - this is called every time a mesh beacon is received. adjust_tbtt() - this is called immediately before a beacon is about to be transmitted. The default neighbor offset synchronization defined in the standard is implemented. We also provide template functions for vendor specific methods. When neighbor offset synchronization is active (which is the default) mesh neighbors in the same MBSS will track timing offsets to each other and compensate clock drift. In our tests we observed that this mesh synchronization implementation successfully corrected drifts between stations of ~2PPM while introducing a jitter of ~20us. It is also possible to test this framework on mac80211_hwsim simulated phys to see how it behaves under different topologies, over poor links, etc. Signed-off-by: Marco Porsch Signed-off-by: Pavel Zubarev Signed-off-by: Javier Cardona Signed-off-by: John W.

This patch implements VIRTIO_NET_F_GUEST_ANNOUNCE feature: hypervisor would notice the guest when it thinks it's time for guest to announce the link presnece. Guest tests VIRTIO_NET_S_ANNOUNCE bit during config change interrupt and woule send gratuitous packets through netif_notify_peers() and ack the notification through ctrl vq. We need to make sure the atomicy of read and ack in guest otherwise we may ack more times than being notified.

The NTF_SELF flag will push the PF_BRIDGE commands to the device. In the basic example below the commands are then parsed and programmed in the embedded bridge. Note if both NTF_SELF and NTF_MASTER bits are set then the command will be sent to both 'dev->master' and 'dev' this allows user space to easily keep the embedded bridge and software bridge in sync. There is a slight complication in the case with both flags set when an error occurs. To resolve this the rtnl handler clears the NTF_ flag in the netlink ack to indicate which sets completed successfully. The add/del handlers will abort as soon as any error occurs. To support this new net device ops were added to call into the device and the existing bridging code was refactored to use these. There should be no required changes in user space to support the current bridge behavior. A basic setup with a SR-IOV enabled NIC looks like this, veth0 veth2 | | ------------ | bridge0 | <---- software bridging ------------ / / ethx.y ethx VF PF \ \ <---- propagate FDB entries to HW \ \ -------------------- | Embedded Bridge | <---- hardware offloaded switching -------------------- In this case the embedded bridge must be managed to allow 'veth0' to communicate with 'ethx.y' correctly. At present drivers managing the embedded bridge either send frames onto the network which then get dropped by the switch OR the embedded bridge will flood these frames. With this patch we have a mechanism to manage the embedded bridge correctly from user space. This example is specific to SR-IOV but replacing the VF with another PF or dropping this into the DSA framework generates similar management issues. Examples session using the 'br'[1] tool to add, dump and then delete a mac address with a new "embedded" option and enabled ixgbe driver: # br fdb add 22:35:19:ac:60:59 dev eth3 # br fdb port mac addr flags veth0 22:35:19:ac:60:58 static veth0 9a:5f:81:f7:f6:ec local eth3 00:1b:21:55:23:59 local eth3 22:35:19:ac:60:59 static veth0 22:35:19:ac:60:57 static #br fdb add 22:35:19:ac:60:59 embedded dev eth3 #br fdb port mac addr flags veth0 22:35:19:ac:60:58 static veth0 9a:5f:81:f7:f6:ec local eth3 00:1b:21:55:23:59 local eth3 22:35:19:ac:60:59 static veth0 22:35:19:ac:60:57 static eth3 22:35:19:ac:60:59 local embedded #br fdb del 22:35:19:ac:60:59 embedded dev eth3 I added a couple lines to 'br' to set the flags correctly is all. It is my opinion that the merit of this patch is now embedded and SW bridges can both be modeled correctly in user space using very nearly the same message passing. [1] 'br' tool was published as an RFC here and will be renamed 'bridge' http://patchwork.ozlabs.org/patch/117664/ Thanks to Jamal Hadi Salim, Stephen Hemminger and Ben Hutchings for valuable feedback, suggestions, and review. v2: fixed api descriptions and error case with both NTF_SELF and NTF_MASTER set plus updated patch description.

Additionally a flags field was added and a NOPROMISC bit to allow users to use passthru mode without the driver calling dev_set_promiscuity(). The flags field is a u16 placed in a 4 byte hole (consuming 2 bytes) of the macvlan_dev struct. We want to do this so that the macvlan driver or stack above the macvlan driver does not have to process every packet. For the use case where we know all the MAC addresses of the endstations above us this works well. This patch is a result of Roopa Prabhu's work. Follow up patches are needed for VEPA and VEB macvlan modes. v2: Change from distinct nopromisc mode to a flags field to configure this. This avoids the tendency to add a new mode every time we need some slightly different behavior. v3: fix error in dev_set_promiscuity and add change and get link attributes for flags.

Need to resurrect them on a socket while repairing. A new sockoption accepts a buffer and parses it. The buffer should be CODE:VALUE sequence of bytes, where CODE is standard option code and VALUE is the respective value. Only 4 options should be handled on repaired socket. To read 3 out of 4 of these options the TCP_INFO sockoption can be used. An ability to get the last one (the mss_clamp) was added by the previous patch. Now the restore. Three of these options -- timestamp_ok, mss_clamp and snd_wscale -- are just restored on a coket. The sack_ok flags has 2 issues. First, whether or not to do sacks at all. This flag is just read and set back. No other sack info is saved or restored, since according to the standart and the code dropping all sack-ed segments is OK, the sender will resubmit them again, so after the repair we will probably experience a pause in connection. Next, the fack bit. It's just set back on a socket if the respective sysctl is set. No collected stats about packets flow is preserved. As far as I see (plz, correct me if I'm wrong) the fack-based congestion algorithm survives dropping all of the stats and repairs itself eventually, probably losing the performance for that period.

This is convenient but has the drawback the data cannot be converted to a page fragment if needed. We have three spots were it hurts : 1) GRO aggregation When a linear skb must be appended to another skb, GRO uses the frag_list fallback, very inefficient since we keep all struct sk_buff around. So drivers enabling GRO but delivering linear skbs to network stack aren't enabling full GRO power. 2) splice(socket -> pipe). We must copy the linear part to a page fragment. This kind of defeats splice() purpose (zero copy claim) 3) TCP coalescing. Recently introduced, this permits to group several contiguous segments into a single skb. This shortens queue lengths and save kernel memory, and greatly reduce probabilities of TCP collapses. This coalescing doesnt work on linear skbs (or we would need to copy data, this would be too slow) Given all these issues, the following patch introduces the possibility of having skb->head be a fragment in itself. We use a new skb flag, skb->head_frag to carry this information. build_skb() is changed to accept a frag_size argument. Drivers willing to provide a page fragment instead of kmalloc() data will set a non zero value, set to the fragment size. Then, on situations we need to convert the skb head to a frag in itself, we can check if skb->head_frag is set and avoid the copies or various fallbacks we have. This means drivers currently using frags could be updated to avoid the current skb->head allocation and reduce their memory footprint (aka skb truesize). (thats 512 or 1024 bytes saved per skb). This also makes bpf/netfilter faster since the 'first frag' will be part of skb linear part, no need to copy data.

It reduces DUPACK threshold (dupthresh) if outstanding packets are less than 4 to recover losses by fast recovery instead of timeout. While the algorithm is simple, small but frequent network reordering makes this feature dangerous: the connection repeatedly enter false recovery and degrade performance. Therefore we implement a mitigation suggested in the appendix of the RFC that delays entering fast recovery by a small interval, i.e., RTT/4. Currently ER is conservative and is disabled for the rest of the connection after the first reordering event. A large scale web server experiment on the performance impact of ER is summarized in section 6 of the paper "Proportional Rate Reduction for TCP”, IMC 2011. http://conferences.sigcomm.org/imc/2011/docs/p155.pdf Note that Linux has a similar feature called THIN_DUPACK. The differences are THIN_DUPACK do not mitigate reorderings and is only used after slow start. Currently ER is disabled if THIN_DUPACK is enabled. I would be happy to merge THIN_DUPACK feature with ER if people think it's a good idea. ER is enabled by sysctl_tcp_early_retrans: 0: Disables ER 1: Reduce dupthresh to packets_out - 1 when outstanding packets < 4. 2: (Default) reduce dupthresh like mode 1.

Add of_mdio_find_bus() which allows an mii_bus to be located given its associated the device tree node. This is needed by the follow-on patch to add a driver for MDIO bus multiplexers. The of_mdiobus_register() function is modified so that the device tree node is recorded in the mii_bus. Then we can find it again by iterating over all mdio_bus_class devices. Because the OF device tree has now become an integral part of the kernel, this can live in mdio_bus.c (which contains the needed mdio_bus_class structure) instead of of_mdio.c.

This patch adds a somewhat generic framework for MDIO bus multiplexers. It is modeled on the I2C multiplexer. The multiplexer is needed if there are multiple PHYs with the same address connected to the same MDIO bus adepter, or if there is insufficient electrical drive capability for all the connected PHY devices. Conceptually it could look something like this: ------------------ | Control Signal | --------+--------- | --------------- --------+------ | MDIO MASTER |---| Multiplexer | --------------- --+-------+---- | | C C h h i i l l d d | | --------- A B --------- | | | | | | | PHY@1 +-------+ +---+ PHY@1 | | | | | | | --------- | | --------- --------- | | --------- | | | | | | | PHY@2 +-------+ +---+ PHY@2 | | | | | --------- --------- This framework configures the bus topology from device tree data. The mechanics of switching the multiplexer is left to device specific drivers. The follow-on patch contains a multiplexer driven by GPIO lines. Signed-off-by: David Daney Signed-off-by: David S.

This problem was hidden behind the automatic helper assignment routine. Thus, it becomes more noticeable now that we can disable the automatic helper assignment with Eric Leblond's: 9e8ac5a netfilter: nf_ct_helper: allow to disable automatic helper assignment Basically, nf_conntrack_alter_reply asks for looking up the helper up if NAT is enabled. Unfortunately, we don't have the conntrack template at that point anymore. Since we don't want to rely on the automatic helper assignment, we can skip the second look-up and stick to the helper that was attached by iptables. With the CT target, the user is in full control of helper attachment, thus, the policy is to trust what the user explicitly configures via iptables (no automatic magic anymore). Interestingly, this bug was hidden by the automatic helper look-up code. But it can be easily trigger if you attach the helper in a non-standard port, eg. iptables -I PREROUTING -t raw -p tcp --dport 8888 \ -j CT --helper ftp And you disabled the automatic helper assignment. I added the IPS_HELPER_BIT that allows us to differenciate between a helper that has been explicitly attached and those that have been automatically assigned. I didn't come up with a better solution (having backward compatibility in mind).

As we don't have infinite memory, we still can drop packets in enqueue() in case of massive load, but mean of CoDel is to drop packets in dequeue(), using a control law based on two simple parameters : target : target sojourn time (default 5ms) interval : width of moving time window (default 100ms) Based on initial work from Dave Taht. Refactored to help future codel inclusion as a plugin for other linux qdisc (FQ_CODEL, ...), like RED. include/net/codel.h contains codel algorithm as close as possible than Kathleen reference. net/sched/sch_codel.c contains the linux qdisc specific glue. Separate structures permit a memory efficient implementation of fq_codel (to be sent as a separate work) : Each flow has its own struct codel_vars. timestamps are taken at enqueue() time with 1024 ns precision, allowing a range of 2199 seconds in queue, and 100Gb links support. iproute2 uses usec as base unit. Selected packets are dropped, unless ECN is enabled and packets can get ECN mark instead. Tested from 2Mb to 10Gb speeds with no particular problems, on ixgbe and tg3 drivers (BQL enabled). Usage: tc qdisc ... codel [ limit PACKETS ] [ target TIME ] [ interval TIME ] [ ecn ] qdisc codel 10: parent 1:1 limit 2000p target 3.0ms interval 60.0ms ecn Sent 13347099587 bytes 8815805 pkt (dropped 0, overlimits 0 requeues 0) rate 202365Kbit 16708pps backlog 113550b 75p requeues 0 count 116 lastcount 98 ldelay 4.3ms dropping drop_next 816us maxpacket 1514 ecn_mark 84399 drop_overlimit 0 CoDel must be seen as a base module, and should be used keeping in mind there is still a FIFO queue. So a typical setup will probably need a hierarchy of several qdiscs and packet classifiers to be able to meet whatever constraints a user might have. One possible example would be to use fq_codel, which combines Fair Queueing and CoDel, in replacement of sfq / sfq_red.

We used to have a similar table with NDIS_* prefix from the gadget driver, but since we're only using RNDIS in the kernel (IIRC NDIS, non-remote, is for the windows- internal network drivers so what do we care) let's prefix everything with RNDIS. Some of the definitions were conflicting, in one of the defines 0x0B is bearer "CO WAN" and in two others "BPC". Well I took the majority vote. Two definition of medium 0x09 calls it "wireless WAN" but one vote for "wireless LAN" but in this case I am sticking with the minority, "Wide Area Network" does not make much sense in this case as far as I can tell. NOTE: latin singular and plural is so screwed up in these defines that it makes my eyes bleed. But I will not attempt to submit a patch converting all use of _MEDIA_ to _MEDIUM_ while I can probably tell from the semantics of the code that RNDIS_MEDIA_STATE_CONNECTED is most probably (erroneously) referring to a singular, unless it can return an array of connected media. I suspect these erroneous plurals are used in documentation and such so I don't want to mess around with things for no functional change. Signed-off-by: Linus Walleij Signed-off-by: David S.

Several tests in the kernel tree use this __ratelimit() function incorrectly. No net_ratelimit uses are incorrect currently though. Most uses of net_ratelimit are to log something via printk or pr_. In order to minimize the uses of net_ratelimit, and to start standardizing the code style used for __ratelimit() and net_ratelimit(), add a net_ratelimited_function() macro and net__ratelimited() logging macros similar to pr__ratelimited that use the global net_ratelimit instead of a static per call site "struct ratelimit_state".

This removes any special processing in the core networking for token ring, (aside from net/tr.c itself), leaving the drivers and remaining tokenring support present but inert. The mass removal of the drivers and net/tr.c will be in a separate commit, so that the history of these files that we still care about won't have the giant deletion tied into their history.

Factorize code so that : __dev_alloc_skb() is a wrapper around __netdev_alloc_skb(), and dev_alloc_skb() a wrapper around netdev_alloc_skb() Use __GFP_COLD flag. Almost all network drivers now benefit from skb->head_frag infrastructure. Signed-off-by: Eric Dumazet Signed-off-by: David S.
