virtio_net: Fix MAX_PACKET_LEN to support 802.1Q VLANs
802.1Q expanded the maximum ethernet frame size by 4 bytes for the
VLAN tag. We're not taking this into account in virtio_net, which
means the buffers we provide to the backend in the virtqueue RX ring
aren't big enough to hold a full MTU VLAN packet. For QEMU/KVM,
this results in the backend exiting with a packet truncation error.

sctp: Fix another socket race during accept/peeloff
There is a race between sctp_rcv() and sctp_accept() where we
have moved the association from the listening socket to the
accepted socket, but sctp_rcv() processing cached the old
socket and continues to use it.
The easy solution is to check for the socket mismatch once we've
grabed the socket lock. If we hit a mis-match, that means
that were are currently holding the lock on the listening socket,
but the association is refrencing a newly accepted socket. We need
to drop the lock on the old socket and grab the lock on the new one.
A more proper solution might be to create accepted sockets when
the new association is established, similar to TCP. That would
eliminate the race for 1-to-1 style sockets, but it would still
existing for 1-to-many sockets where a user wished to peeloff an
association. For now, we'll live with this easy solution as
it addresses the problem.

sctp: Properly timestamp outgoing data chunks for rtx purposes
Recent changes to the retransmit code exposed a long standing
bug where it was possible for a chunk to be time stamped
after the retransmit timer was reset. This caused a rare
situation where the retrnamist timer has expired, but
nothing was marked for retrnasmission because all of
timesamps on data were less then 1 rto ago. As result,
the timer was never restarted since nothing was retransmitted,
and this resulted in a hung association that did couldn't
complete the data transfer. The solution is to timestamp
the chunk when it's added to the packet for transmission
purposes. After the packet is trsnmitted the rtx timer
is restarted. This guarantees that when the timer expires,
there will be data to retransmit.

wimax/i2400m: error paths that need to free an skb should use kfree_skb()
Roel Kluin reported a bug in two error paths where skbs were wrongly
being freed using kfree(). He provided a fix where it was replaced to
kfree_skb(), as it should be.
However, in i2400mu_rx(), the error path was missing returning an
indication of the failure. Changed to reset rx_skb to NULL and return
it to the caller, i2400mu_rxd(). It will be treated as a transient
error and just ignore the packet.
Depending on the buffering conditions inside the device, the data
packet might be dropped or the device will signal the host again for
data-ready-to-read and the host will retry.

mv643xx_eth: prevent interrupt storm on ifconfig down
Contrary to what the docs say, the 'extended interrupt cause' bit in

net: Fix data corruption when splicing from sockets.
The trick in socket splicing where we try to convert the skb->data
into a page based reference using virt_to_page() does not work so
well.
The idea is to pass the virt_to_page() reference via the pipe
buffer, and refcount the buffer using a SKB reference.
But if we are splicing from a socket to a socket (via sendpage)
this doesn't work.
The from side processing will grab the page (and SKB) references.
The sendpage() calls will grab page references only, return, and
then the from side processing completes and drops the SKB ref.
The page based reference to skb->data is not enough to keep the
kmalloc() buffer backing it from being reused. Yet, that is
all that the socket send side has at this point.
This leads to data corruption if the skb->data buffer is reused
by SLAB before the send side socket actually gets the TX packet
out to the device.
The fix employed here is to simply allocate a page and copy the
skb->data bytes into that page.
This will hurt performance, but there is no clear way to fix this
properly without a copy at the present time, and it is important
to get rid of the data corruption.
With fixes from Herbert Xu.

tg3: Fix firmware loading
This patch modifies how the tg3 driver handles device firmware.
The patch starts by consolidating David Woodhouse's earlier patch under
the same name. Specifically, the patch moves the request_firmware call
into a separate tg3_request_firmware() function and calls that function
from tg3_open() rather than tg3_init_one().
The patch then goes on to limit the number of devices that will make
request_firmware calls. The original firmware patch unnecessarily
requested TSO firmware for devices that did not need it. This patch
reduces the set of devices making TSO firmware patches to approximately
the following device set : 5703, 5704, and 5705.
Finally, the patch reduces the effects of a request_firmware() failure.
For those devices that are requesting TSO firmware, the driver will turn
off the TSO capability. If TSO firmware becomes available at a later
time, the device can be closed and then opened again to reacquire the
TSO capability.

fe333321 ("powerpc: Change u64/s64 to a long long integer

rt2x00: fix a wrong parameter for __test_and_clear_bit() in rt2x00rfkill_free().
When running modprobe rt73usb, and then rmmod rt73usb, and then
iwconfig, the wlan0 device does not disappear. When repeating this
process again, we get a kernel Oops errors and "BUG: unable to handle
kernel paging request..." message in the kernel log.
The reason for this is that there is an error in rt2x00rfkill_free(),
which is called in the process of removing the device
(rt2x00lib_remove_dev() in rt2x00dev.c).
rt2x00rfkill_free() clears the RFKILL_STATE_ALLOCATED bit , which is
bit number 1 () in rt2x00dev->flags instead of in
rt2x00dev->rfkill_state. As a result, when checking the
DEVICE_STATE_REGISTERED_HW bit (bit number 1 in rt2x00dev->flags) in
rt2x00lib_remove_hw() it is **unset**, and we wrongly **don't** call
ieee80211_unregister_hw().
This patch corrects this: the parameter for __test_and_clear_bit() in
rt2x00rfkill_free() should be &rt2x00dev->rfkill_state and not
&rt2x00dev->flags.

cfg80211: Fix regression with 11d on bands
This fixes a regression on disallowing bands introduced with the new
802.11d support. The issue is that IEEE-802.11 allows APs to send
a subset of what a country regulatory domain defines. This was clarified
in this document:
http://tinyurl.com/11d-clarification
As such it is possible, and this is what is done in practice, that a
single band 2.4 GHz AP will only send 2.4 GHz band regulatory information
through the 802.11 country information element and then the current
intersection with what CRDA provided yields a regulatory domain with
no 5 GHz information -- even though that country may actually allow
5 GHz operation. We correct this by only applying the intersection rules
on a channel if the the intersection yields a regulatory rule on the
same band the channel is on.
