Since commit a3348722 AFEX FCoE function is continuously reset.
The patch prevents the resetting and removes debug print
to stop garbaging syslog.

vlan: fix bond/team enslave of vlan challenged slave/port

2012-10-16T18:41:46+00:00

In vlan_uses_dev() check for number of vlan devs rather than existence
of vlan_info. The reason is that vlan id 0 is there without appropriate
vlan dev on it by default which prevented from enslaving vlan challenged
dev.

mcs7830: Fix link state detection

2012-10-12T17:56:52+00:00

The device had an undocumented "feature": it can provide a sequence of
spurious link-down status data even if the link is up all the time.
A sequence of 10 was seen so update the link state only after the device
reports the same link state 20 times.

usbnet: Support devices reporting idleness

2012-10-11T19:19:21+00:00

Some device types support a form of power management in which
the device suggests to the host that the device may be suspended
now. Support for that is best located in usbnet.

net/ethernet/jme: disable ASPM

2012-10-11T19:18:49+00:00

Based on patch from Matthew Garrett  (https://lkml.org/lkml/2011/11/11/168).

http://driveragent.com/archive/30421/7-0-14 indicates that ASPM is
disabled on the 250 and 260. Duplicate for sanity.

Fixes random RX engine hangs I experienced with JMC250 on Clevo W270HU.

e1000e: Change wthresh to 1 to avoid possible Tx stalls

2012-10-11T02:59:18+00:00

This patch originated from Hiroaki SHIMODA but has been modified
by Intel with some minor cleanups and additional commit log text.

Denys Fedoryshchenko and others reported Tx stalls on e1000e with
BQL enabled.  Issue was root caused to hardware delays. They were
introduced because some of the e1000e hardware with transmit
writeback bursting enabled, waits until the driver does an
explict flush OR there are WTHRESH descriptors to write back.

Sometimes the delays in question were on the order of seconds,
causing visible lag for ssh sessions and unacceptable tx
completion latency, especially for BQL enabled kernels.

To avoid possible Tx stalls, change WTHRESH back to 1.

The current plan is to investigate a method for re-enabling
WTHRESH while not harming BQL, but those patches will be later
for net-next if they work.

please enqueue for stable since v3.3 as this bug was introduced in

xen: netback: handle compound page fragments on transmit.

2012-10-11T02:50:45+00:00

An SKB paged fragment can consist of a compound page with order > 0.
However the netchannel protocol deals only in PAGE_SIZE frames.

Handle this in netbk_gop_frag_copy and xen_netbk_count_skb_slots by
iterating over the frames which make up the page.

vxlan: fix oops when give unknown ifindex

2012-10-11T02:41:22+00:00

If vxlan is created and the ifindex is passed; there are two cases which
are incorrectly handled by the existing code. The ifindex could be zero
(i.e. no device) or there could be no device with that ifindex.

vxlan: fix receive checksum handling

2012-10-11T02:41:22+00:00

Vxlan was trying to use postpull_rcsum to allow receive checksum
offload to work on drivers using CHECKSUM_COMPLETE method. But this
doesn't work correctly. Just force full receive checksum on received
packet.
