In commit 2da31939a42f7a676a0bc5155d6a0a39ed8451f2, support
for Bluetooth hid_output_raw_report was added, but it pushes
the data to the interrupt channel instead of the contol one.
This patch makes hid_output_raw_report use the control channel
instead. Using the interrupt channel was a mistake.

Commit ac019360fe3 changed the irq handler logic to BUG_ON rather than
returning IRQ_NONE when the incoming argument is invalid. While this
works in most cases, it doesn't work when the IRQ is shared with other
devices (or when DEBUG_SHIRQ is enabled).
So revert the previous change and replace the warning message with a
comment explaining that we want this behavior.

Commit 37e8273cd30592d3a82bcb70cbb1bdc4eaeb6b71 ("usbnet: Set link down
initially for drivers that update link state") changed the initial link
state in cdc_ether and other drivers based on the understanding that the
devices they support generate link change interrupts. However, this is
optional in the CDC Ethernet protocol, and two users have reported in
<http://bugzilla.kernel.org/show_bug.cgi?id=14791> that the link state
for their devices remains down. Therefore, revert the change in
cdc_ether.

we can learn if this is going to fail as early as possible. Previously,
ixgbe_down or ixgbe_close were being called before this check and the

ath9k: Enable Fractional N mode
changed the hw attach code to fix up initialization values only for
dual band devices, however the commit message did not give a reason as
to why this would be useful or necessary.
According to tests by Jorge Boncompte, this breaks at least some
2GHz-only cards, so the code should be changed back to the
unconditional INI fixup.

When cleaning up beacon buffers and slots, ath9k currently checks if
sc->ah->opmode is set to a beacon related mode before cleaning up
buffers.
An unfortunate ordering of interface up/down commands can lead to
sc->ah->opmode being set to monitor mode, while there are AP interfaces
present on the same wiphy.
Always cleaning up beacon buffers if present fixes this issue.

netdev_open() will return without cleaning up net device or hardware state
if firmware loading fails. This results in a BUG() on a second attempt to
bring the interface up, reported in
<http://bugzilla.kernel.org/show_bug.cgi?id=15091>, and probably has even
worse effects if the driver is removed afterwards.
Call netdev_close() to clean up on failure.

The commit 0b5ccb2(title:ipv6: reassembly: use seperate reassembly queues for
conntrack and local delivery) has broken the saddr&&daddr member of
nf_ct_frag6_queue when creating new queue. And then hash value
generated by nf_hashfn() was not equal with that generated by fq_find().
So, a new received fragment can't be inserted to right queue.
The patch fixes the bug with adding member of user to nf_ct_frag6_queue structure.

I have seen RX stalls on a machine that experienced a suspected
OOM. After the stall, the RX buffer is empty on the guest side
and there are exactly 16 entries available on the host side. As
the number of entries is less than that required by a maximal
skb, the host cannot proceed.
The guest did not have a refill job scheduled.
My diagnosis is that an OOM had occured, with the delayed refill
job scheduled. The job was able to allocate at least one skb, but
not enough to overcome the minimum required by the host to proceed.
As the refill job would only reschedule itself if it failed completely
to allocate any skbs, this would lead to an RX stall.
The following patch removes this stall possibility by always
rescheduling the refill job until the ring is totally refilled.
Testing has shown that the RX stall no longer occurs whereas
previously it would occur within a day.

The low-level MCDI code always uses 32-bit MMIO operations, and
callers must pad input and output buffers to multiples of 4 bytes.
The MCDI NVRAM functions are not doing this. Also, their buffers are
declared as variable-length arrays with no explicit maximum length.
Switch to a fixed buffer size based on the chunk size used by the
MTD driver (which is a multiple of 4).

Due to a hardware bug in the SFC9000 family, the firmware must
transfer raw GMAC statistics to host memory before aggregating them
into the cooked (speed-independent) MAC statistics. Extend the stats
buffer to support this.
The length of the buffer is explicit in the MAC_STATS command, so this
change is backward-compatible on both sides.

GC is non-existent in netns, so after you hit GC threshold, no new
dst entries will be created until someone triggers cleanup in init_net.
Make xfrm4_dst_ops and xfrm6_dst_ops per-netns.
This is not done in a generic way, because it woule waste
(AF_MAX - 2) * sizeof(struct dst_ops) bytes per-netns.
Reorder GC threshold initialization so it'd be done before registering
XFRM policies.

When testing the "e1000: enhance frame fragment detection" (and e1000e)
patches we found some bugs with reducing the MTU size. The 1024 byte
descriptor used with the 1000 mtu test also (re) introduced the
(originally) reported bug, and causes us to need the e1000_clean_tx_irq
"enhance frame fragment detection" fix.
So what has occured here is that 2.6.32 is only vulnerable for mtu <
1500 due to the jumbo specific routines in both e1000 and e1000e.
So, 2.6.32 needs the 2kB buffer len fix for those smaller MTUs, but
is not vulnerable to the original issue reported. It has been pointed
out that this vulnerability needs to be patched in older kernels that
don't have the e1000 jumbo routine. Without the jumbo routines, we
need the "enhance frame fragment detection" fix the e1000, old
e1000e is only vulnerable for < 1500 mtu, and needs a similar
fix. We split the patches up to provide easy backport paths.
There is only a slight bit of extra code when this fix and the
original "enhance frame fragment detection" fixes are applied, so
please apply both, even though it is a bit of overkill.

Please add support for Microsoft MN-120 PCMCIA network card. It's an
old card, I know, but adding support is very easy. You just need to
get tulip_core.c to recognise its vendor/device ID.
Patch for kernel 2.6.32.4 (and many previous) attached.

The Intel WiMax Wireless Link 6050 can show under more than one USB
ID. Add support for all, introducing a generic flag (i2400mu->i6050)
that denotes a 6x50 based device.

The is_software_event() definition always confuses me because its an
exclusive expression, make it an inclusive one.
