The mvneta driver and hardware supports IPv6 offload, however it
isn't enabled. Set the NETIF_F_IPV6_CSUM feature to inform the
network layer that this driver can offload IPV6 TCP and UDP
checksums. This change has been tested on an Armada 370 and the
feature support confirmed with several device datasheets
including the Armada XP and Armada 3700.

At the end of the do while loop the integer counter retries will
always be zero and so the subsequent check to see if it is zero
is always true and therefore redundant. Remove the redundant check
and always return -EIO on this return path. Also unbreak the literal
string in dev_err message to clean up a checkpatch warning.

mdio_mux_uninit() call put_device (unconditionally) because of
of_mdio_find_bus() in mdio_mux_init.
But of_mdio_find_bus is only called if mux_bus is empty.
If mux_bus is set, mdio_mux_uninit will print a "refcount_t: underflow"
trace.
This patch add a get_device in the other branch of "if (mux_bus)".

This patch adds the GoP link interrupt support for when a port isn't
connected to a PHY. Because of this the phylib callback is never called
and the link status management isn't done. This patch use the GoP link
interrupt in such cases to still have a minimal link management. Without
this patch ports not connected to a PHY cannot work.

There is not necessarily a PHY between the GoP and the physical port.
However, the driver currently makes the "phy" property mandatory,
contrary to what is stated in the device tree bindings. This patch makes
the PHY optional, and aligns the PPv2 driver on its device tree
documentation. However if a PHY is provided, the GoP link interrupt
won't be used.
With this patch switches directly connected to the serdes lanes and SFP
ports on the Armada 8040-db and Armada 7040-db can be used if the link
interrupt is described in the device tree.

When the abort mechanism is invoked a default route directing packets to
the CPU is programmed in all the virtual routers currently in use. This
can result in packet loss in case a new VRF is configured.
Upon abort, program the default route in all virtual routers, whether
they are in use or not.
The patch is directed at net-next since post-abort fixes aren't critical
and packet loss due to a missing default route will be insignificant
compared to packet loss caused by the CPU port policer.

I relied on the fact that anycast routes use the loopback device as
their nexthop device to trap packets hitting them to the CPU.
After commit 4832c30d5458 ("net: ipv6: put host and anycast routes on
device with address") this is no longer the case and such routes are
programmed with a forward action (note the 'offload' flag):
anycast cafe:: dev enp3s0np7 proto kernel metric 0 offload pref medium
This will prevent the router from locally receiving packets destined to
the Subnet-Router anycast address.
Fix this by specifically programming anycast routes with action trap,
which results in the following output:
anycast cafe:: dev enp3s0np7 proto kernel metric 0 pref medium

ACPI will rely on device driver to tell it if the device could support
wakeup function when system in D3 state.
This has caused some platform can't support remote wakeup correctly,
because the ACPI wakeup GPE is not enabled, hence registers the .set_wakeup
callback to handle it if device supports wakeup.

In commit 9f5bcfe93315 ("ath10k: silence firmware file probing
warnings") the firmware loading was changed from request_firmware() to
request_firmware_direct() to silence some warnings in case it fails.
request_firmware_direct() directly searches in the file system only and
does not send a hotplug event to user space in case it could not find
the firmware directly.
In LEDE we use a user space script to extract the calibration data from
the flash memory which gets triggered by the hotplug event. This way the
firmware gets extracted from some vendor specific partition when the
driver requests this firmware. This mechanism does not work any more
after this change.

In napi_poll, the budget number is used to control the amount of packets
we should handle per poll to balance the resource in the system.
In the list of the amsdu packets reception, we check if there is budget
count left and handle the complete list of the packets, that it will have
chances the very last list will over the budget leftover.
So adding one more parameter - budget_left, this would help while
traversing the list to avoid handling more than the budget given.

mlx5-updates-2017-08-31 (GRE Offloads support)
This series provides the support for MPLS RSS and GRE TX offloads and
RSS support.
The first patch from Gal and Ariel provides the mlx5 driver support for
ConnectX capability to perform IP version identification and matching in
order to distinguish between IPv4 and IPv6 without the need to specify the
encapsulation type, thus perform RSS in MPLS automatically without
specifying MPLS ethertyoe. This patch will also serve for inner GRE IPv4/6
classification for inner GRE RSS.
2nd patch from Gal, Adds the TX offloads support for GRE tunneled packets,
by reporting the needed netdev features.
3rd patch from Gal, Adds GRE inner RSS support by creating the needed device
resources (Steering Tables/rules and traffic classifiers) to Match GRE traffic
and perform RSS hashing on the inner headers.

Fix crash in linux PF driver when BARs have been cleared/de-programmed;
fail early init (prior to mapping BARs) if the BAR0 or
BAR1 registers are zero.
This situation can arise when the PF is added to a VM (PCI pass-through),
then a PF FLR is issued (in the VM). After this occurs, the BAR registers
will be zero. If we attempt to load the PF driver in the host
(after VM has been shutdown), the host can reset.

Introduce a new flow table and indirect TIRs which are used to hash the
inner packet headers of GRE tunneled packets.
When a GRE tunneled packet is received, the TTC flow table will match
the new IPv4/6->GRE rules which will forward it to the inner TTC table.
The inner TTC is similar to its counterpart outer TTC table, but
matching the inner packet headers instead of the outer ones (and does
not include the new IPv4/6->GRE rules).
The new rules will not add steering hops since they are added to an
already existing flow group which will be matched regardless of this
patch. Non GRE traffic will not be affected.
The inner flow table will forward the packet to inner indirect TIRs
which hash the inner packet and thus result in RSS for the tunneled
packets.

This change adds the ability for flow steering to classify IPv4/6
packets with MPLS tag (Ethertype 0x8847 and 0x8848) as standard IP
packets and hit IPv4/6 classification steering rules.
Since IP packets with MPLS tag header have MPLS ethertype, they
missed the IPv4/6 ethertype rule and ended up hitting the default
filter forwarding all the packets to the same single RQ (No RSS).
Since our device is able to look past the MPLS tag and identify the
next protocol we introduce this solution which replaces ethertype
matching by the device's capability to perform IP version
identification and matching in order to distinguish between IPv4 and
IPv6.
Therefore, when driver is performing flow steering configuration on the
device it will use IP version matching in IP classified rules instead
of ethertype matching which will cause relevant MPLS tagged packets to
hit this rule as well.
If the device doesn't support IP version matching the driver will fall back
to use legacy ethertype matching in the steering as before.
