06b71b657b netdev: usb: dm9601.c can drive a device not supported yet, add support for it
I found that the current version of drivers/net/usb/dm9601.c can be used to
successfully drive a low-power, low-cost network adapter with USB ID
0a46:9000, based on a DM9000E chipset. As no device with this ID is yet
present in the kernel, I have created a patch that adds support for the device
to the dm9601 driver.

Created and tested against linux-2.6.32-rc5.

d9d5283228 bonding: fix a race condition in calls to slave MII ioctls
In mii monitor mode, bond_check_dev_link() calls the the ioctl
handler of slave devices. It stores the ndo_do_ioctl function
pointer to a static (!) ioctl variable and later uses it to call the
handler with the IOCTL macro.

If another thread executes bond_check_dev_link() at the same time
(even with a different bond, which none of the locks prevent), a
race condition occurs. If the two racing slaves have different
drivers, this may result in one driver's ioctl handler being
called with a pointer to a net_device controlled with a different
driver, resulting in unpredictable breakage.

Unless I am overlooking something, the "static" must be a
copy'n'paste error (?).

03f191bab7 virtio-net: fix data corruption with OOM
virtio net used to unlink skbs from send queues on error,
but ever since 48925e372f
we do not do this. This causes guest data corruption and crashes
with vhost since net core can requeue the skb or free it without
it being taken off the list.

This patch fixes this by queueing the skb after successful
transmit.

d50bae33d1 b43: Fix Bugzilla #14181 and the bug from the previous 'fix'
"b43: Fix PPC crash in rfkill polling on unload" fixed the bug reported
in Bugzilla No. 14181; however, it introduced a new bug. Whenever the
radio switch was turned off, it was necessary to unload and reload
the driver for it to recognize the switch again.

This patch fixes both the original bug in #14181 and the bug introduced by
the previous patch. It must be stated, however, that if there is a BCM4306/3
with an rfkill switch (not yet proven), then the driver will need an
unload/reload cycle to turn the device back on.

fb64bb560e PPPoE: Fix flush/close races.
Be more careful about the state of pointers during tear-down.
The "pppoe_dev" field can only be looked at safely while holding socket locks.
This subsequently allows for the flush_lock to be killed.

We depend on the PPPOX_CONNECTED state to tell us that that those fields are
valid, so whoever clears that state (pppox_unbind_sock()) is responsible for
the dev_put() call.

We also have to ensure that we delete_item() on all sockets before they are
cleaned up.

The need for these changes has been exposed by scenarios wherein namespace
bindings of ethernet devices change while there are ongoing PPPoE sessions,
which resulted in oopses due to unusual socket connection termination paths,
exposing these issues.

5ccdcecb72 e1000e: allow for swflag to be held over consecutive PHY accesses
PCH-based parts (82577/82578) and some ICH8-based parts (82566) need to
hold the swflag (sw/fw/hw hardware semaphore) over consecutive PHY accesses
in order to perform sw-driven PHY configuration during initialization to
workaround known hardware issues (see follow-on patch).  This patch
provides new PHY read/write functions (and function pointers) that will
allow accessing the PHY registers assuming the swflag has already been
acquired.  The actual PHY register access code has moved into helper
functions that are called with a flag indicating whether or not the swflag
has already been acquired and acquires/releases it if not.

The functions called from within the updated PHY access functions had to be
updated to assume the swflag was already acquired, and other functions that
called those functions were also updated to acquire/release the swflag.

Accesses to NVM and PHY/CSR registers on ICHx/PCH-based parts are protected
from concurrent accesses with a mutex that is acquired when the access is
initiated and released when the access has completed.  However, the two
types of accesses should not be protected by the same mutex because the
driver may have to access the NVM while already holding the mutex over
several consecutive PHY/CSR accesses which would result in livelock.

05af2142d0 r8169: fix Ethernet Hangup for RTL8110SC rev d
The 8110SC rev d chip on our board shows a regression which the 8110SB chip
did not have. When inbound traffic is overflowing the receive descriptor queue,
"holes" in the ring buffer may occur which lead to a hangup until the buffer
is filled again. The packets are than completely processed, but the ring
remains porous and no packets are processed until the next overflow. Setting
the interface down and up can fix the problem temporary from userspace.

For some reason we don't know, this behaviour is not occuring if the RxVlan
bit for hardware VLAN untagging is set. There is another "Work around for
AMD plateform" in the current code which checks the VLAN status
word in receive descriptors, but does never come to effect when hardware
VLAN support is enabled. We assume that this is a bug in the chip.

The following patch fixes the problem. Without the patch we could reproduce
the hang within minutes (given other devices also generating lots of
interrupts), without we couldn't reproduce within a few days of long term
testing.

This version contains minor style adjustments and is sent with mutt which
will hopefully not destroy the formatting again.

The PHY on 82577/82578 parts needs a soft reset when transitioning to Sx
state in order for the PHY write which disables gigabit speed to take
effect.  Gigabit speed must be disabled in order for the PHY writes to

otherwise the system might not wake via WoL.

e95646c3ec virtio: let header files include virtio_ids.h
Rusty,

commit 3ca4f5ca73
    virtio: add virtio IDs file
moved all device IDs into a single file. While the change itself is
a very good one, it can break userspace applications. For example
if a userspace tool wanted to get the ID of virtio_net it used to
include virtio_net.h. This does no longer work, since virtio_net.h
does not include virtio_ids.h.
This patch moves all "#include <linux/virtio_ids.h>" from the C
files into the header files, making the header files compatible with
the old ones.

In addition, this patch exports virtio_ids.h to userspace.

b6a71bfa00 KS8851: Fix ks8851_set_rx_mode() for IFF_MULTICAST
In ks8851_set_rx_mode() the case handling IFF_MULTICAST was also setting
the RXCR1_AE bit by accident. This meant that all unicast frames where
being accepted by the device. Remove RXCR1_AE from this case.

Note, RXCR1_AE was also masking a problem with setting the MAC address
properly, so needs to be applied after fixing the MAC write order.

Fixes a bug reported by Doong, Ping of Micrel. This version of the
patch avoids setting RXCR1_ME for all cases.
