2012-10-02sfc: Fix MCDI structure field lookupBen Hutchings
The least significant bit number (LBN) of a field within an MCDI structure is counted from the start of the structure, not the containing dword. In MCDI_ARRAY_FIELD() we need to mask it rather than using the usual EFX_DWORD_FIELD() macro. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

2012-10-02sfc: Fix null function pointer in efx_sriov_channel_typeBen Hutchings
Commit c31e5f9 ('sfc: Add channel specific receive_skb handler and post_remove callback') added the function pointer field efx_channel_type::post_remove and an unconditional call through it. This field should have been initialised to efx_channel_dummy_op_void in the existing instances of efx_channel_type, but this was only done in efx_default_channel_type. Consequently, if a device has SR-IOV enabled then removing the driver or device will result in an oops. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

2012-09-21net: qmi_wwan: adding Huawei E367, ZTE MF683 and Pantech P4200Bjørn Mork
One of the modes of Huawei E367 has this QMI/wwan interface: I:* If#= 1 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=01 Prot=07 Driver=(none) E: Ad=83(I) Atr=03(Int.)

The Pantech devices UML290 (106c:3718) and P4200 (106c:3721) use the same subclass to identify the QMI/wwan function. Replace the existing device specific UML290 entries with generic vendor matching, adding support for the Pantech P4200. The ZTE MF683 has 6 vendor specific interfaces, all using ff/ff/ff for cls/sub/prot. Adding a match on interface #5 which is a QMI/wwan interface.

2012-09-20USB: remove dbg() usage in USB networking driversGreg Kroah-Hartman
The dbg() USB macro is so old, it predates me. The USB networking drivers are the last hold-out using this macro, and we want to get rid of it, so replace the usage of it with the proper netdev_dbg() or dev_dbg() (depending on the context) calls. Some places we end up using a local variable for the debug call, so also convert the other existing dev_* calls to use it as well, to save tiny amounts of code space.

2012-09-20IB/ipoib: Add rtnl_link_ops supportOr Gerlitz
Add rtnl_link_ops to IPoIB, with the first usage being child device create/delete through them. Childs devices are now either legacy ones, created/deleted through the ipoib sysfs entries, or RTNL ones. Adding support for RTNL childs involved refactoring of ipoib_vlan_add which is now used by both the sysfs and the link_ops code. Also, added ndo_uninit entry to support calling unregister_netdevice_queue from the rtnl dellink entry. This required removal of calls to ipoib_dev_cleanup from the driver in flows which use unregister_netdevice, since the networking core will invoke ipoib_uninit which does exactly that.

2012-09-19r8169: use unlimited DMA burst for TXMichal Schmidt
The r8169 driver currently limits the DMA burst for TX to 1024 bytes. I have a box where this prevents the interface from using the gigabit line to its full potential. This patch solves the problem by setting TX_DMA_BURST to unlimited. The box has an ASRock B75M motherboard with on-board RTL8168evl/8111evl (XID 0c900880). TSO is enabled. I used netperf (TCP_STREAM test) to measure the dependency of TX throughput on MTU. I did it for three different values of TX_DMA_BURST ('5'=512, '6'=1024, '7'=unlimited). This chart shows the results: http://michich.fedorapeople.org/r8169/r8169-effects-of-TX_DMA_BURST.png Interesting points: - With the current DMA burst limit (1024): - at the default MTU=1500 I get only 842 Mbit/s. - when going from small MTU, the performance rises monotonically with increasing MTU only up to a peak at MTU=1076 (908 MBit/s). Then there's a sudden drop to 762 MBit/s from which the throughput rises monotonically again with further MTU increases. - With a smaller DMA burst limit (512): - there's a similar peak at MTU=1076 and another one at MTU=564. - With unlimited DMA burst: - at the default MTU=1500 I get nice 940 Mbit/s. - the throughput rises monotonically with increasing MTU with no strange peaks. Notice that the peaks occur at MTU sizes that are multiples of the DMA burst limit plus 52. Why 52? Because: 20 (IP header) + 20 (TCP header) + 12 (TCP options) = 52 The Realtek-provided r8168 driver (v8.032.00) uses unlimited TX DMA burst too, except for CFG_METHOD_1 where the TX DMA burst is set to 512 bytes. CFG_METHOD_1 appears to be the oldest MAC version of "RTL8168B/8111B", i.e. RTL_GIGA_MAC_VER_11 in r8169. Not sure if this MAC version really needs the smaller burst limit, or if any other versions have similar requirements.

2012-09-19sfc: Avoid generating over-length MC_CMD_FLUSH_RX_QUEUES requestBen Hutchings
MCDI supports requests up to 252 bytes long, which is only enough to pass 63 RX queue IDs to MC_CMD_FLUSH_RX_QUEUES. However a VF may have up to 64 RX queues, and if we try to flush them all we will generate an over-length request and BUG() in efx_mcdi_copyin(). Currently all VF drivers limit themselves to 32 RX queues, so reducing the limit to 63 does no harm. Also add a BUILD_BUG_ON in efx_mcdi_flush_rxqs() so we remember to deal with the same problem there if EFX_MAX_CHANNELS is increased. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

Conflicts: net/netfilter/nfnetlink_log.c net/netfilter/xt_LOG.c Rather easy conflict resolution, the 'net' tree had bug fixes to make sure we checked if a socket is a time-wait one or not and elide the logging code if so. Whereas on the 'net-next' side we are calculating the UID and GID from the creds using different interfaces due to the user namespace changes from Eric Biederman. Signed-off-by: David S.

Pull drm fixes from Dave Airlie: "I realise this a bit bigger than I would want at this point.
