drivers/net/wireless/b43/main.c: In function ‘b43_op_config’:
drivers/net/wireless/b43/main.c:3264: warning: ‘gmode’ may be used uninitialized

The commits:
7a95d267fb62cd6b80ef73be0592bbbe1dbd5df7
("net: ppp_generic - use idr technique instead of cardmaps")
ab5024ab23b78c86a0a1425defcdde48710fe449
("net: ppp_generic - use DEFINE_IDR for static initialization")
introduced usage of IDR functionality but broke userspace side.
Before this commits it was possible to allocate new ppp interface with
specified number. Now it fails with EINVAL. Fix it by trying to
allocate interface with specified unit number and return EEXIST if
fail which allow pppd to ask us to allocate new unit number.
And fix messages on memory allocation fails - add details that it's
PPP module who is complaining.

The bug introduced by commit 8c7396aebb68994c0519e438eecdf4d5fa9c7844
("gianfar: Merge Tx and Rx interrupt for scheduling clean up ring").
The commit merged TX and RX interrupt code into a single routine that
schedules NAPI, but no locks were introduced. This causes irq races, so
when irqs are enabled and netif_rx_schedule_prep() returns 0, nobody
disable the interrupts again. This leads to interrupt storm and finally
to the lockup.

The TXD_W0_CIPHER field is a 1-bit field. It only acts as boolean value
to indicate if the frame must be encrypted or not.
The way rt2x00_set_field32() worked it would grab the least signifcant bit
from txdesc->cipher and use that as value. Because of that WEP 64 and TKIP
worked since they had odd-numbered values, while WEP 128 and AES were
even numbers and didn't work.
Correctly booleanize the txdecs->cipher value to allow the hardware to
encrypt the outgoing data. After this we can enable HW crypto by default again.

Due to misunderstanding of the returned values allowed for the tx callback
of mac80211, rtl8187 was using skb's that had been freed. This problem was
triggered when the module was sujected to a rmmod/insmod cycle.
After that was fixed, the modules would not work after the rmmod/insmod cycle
until the USB device was reset.

This patch reverts "ath9k: Fix TX status reporting for retries and MCS index"
because that change ended up breaking ath9k rate control. While the
MCS index reporting to mac80211 was indeed fixed by the patch, it did
not take into account that the ath9k rate control algorithm was
updating private tables based on this index and the index comes
through the rate control API call, i.e., based on mac80211 TX status
call. In addition, it looks like the "fix" to remove +1 from TX status
'count' field was not correct based on ieee80211_tx_status()
implementation that counts the total of count values, but starting
from -1, not 0.
The TX status reporting for frames using MCS needs to be fixed
somehow, but it does not look like there is any easy fix for the ath9k
rate control algorithm, so the best option now seems to be to revert the
change and bring it back once the rate control code is cleaned up to
handle this better.

rt2500usb doesn't strip the IV/ICV data from received frames,
so we don't need to set the RX_FLAG_IV_STRIPPED flag.
We do need to set the RX_FLAG_MMIC_STRIPPED flag for all

The queue_end() macro points to 1 position after the
queue, which means that if we want to know if queue
is at the end of the queue we should first increment
the position and then check if it is a valid entry.
This fixes a segmentation fault which only occurs when
the device has enough endpoints to provide a dedicated
endpoint for all TX queues (which likely won't happen
for rt2500usb and rt73usb, but will happen for rt2800usb).

Fix the warning reproduced below.
We add to rx_list in interrupt context and remove elements in tasklet
context. While removing elements we need to prevent the interrupt
modifying the list.
Note that "orinoco: Process bulk of receive interrupt in a tasklet" did not
preserve locking semantics on what is now orinoco_rx.
This patch reinstates the locking semantics and ensures it covers
rx_list as well. This leads to additional cleanup required in
free_orinocodev.

I have a system with a Chelsio adapter (driven by cxgb3) whose ports are
part of a Linux bridge. Recently I updated the kernel and discovered
that things stopped working because cxgb3 was doing LRO on packets that
were passed into the bridge code for forwarding. (Incidentally, this
problem manifested itself in a strange way that made debugging a bit
interesting -- for some reason, the skb_warn_if_lro() check in bridge
didn't trigger and these LROed packets were forwarded out a forcedeth
interface, and caused the forcedeth transmit path to get stuck)
This is because cxgb3 has no way of keeping state for the LRO flag until
the interface is brought up, so if the bridging code disables LRO while
the interface is down, then cxgb3_up() will just reenable LRO, and on my
Debian system at least, the init scripts add interfaces to a bridge
before bringing the interfaces up.
Fix this by keeping track of each interface's LRO state in cxgb3 so that
when bridge disables LRO, it stays disabled in cxgb3_up() when the
interface is brought up. I did this by changing the rx_csum_offload
flag into a pair of bit flags; the effect of this on the rx_eth() fast
path is miniscule enough that it should be fine (eg on x86, a cmpb
instruction becomes a testb instruction).

Only the SFX7101 requires software power control. This was
incorrectly being applied to the SFT9001 rev A as well.

This change lets "cat /proc/interrupts" show the name of the ethernet
device (e.g. eth0) rather than the driver name (smsc911x).

if this code path is ever hit, the platform_data struct isn't properly
configured with a bus width flag so the device won't work (hence the
BUG()).
This patch adds a dummy return statement to eliminate this compiler
warning:
drivers/net/smsc911x.c: In function 'smsc911x_reg_read':
drivers/net/smsc911x.c:148: warning: control reaches end of non-void function

This patch fixes a potential race condition between scheduling napi and
completing napi poll. The call to netif_rx_schedule should be under
protection of the lock (as is the completion), otherwise, interrupts
could be masked off.

This patch fixes a potential race condition between xmit thread and xmit
completion thread. The calculation of empty tx descriptors is not
performed under the lock. This could cause it to set the stop flag while
the completion thread finishes all tx's. This will result in the tx
queue in stopped state and no one to wake it up.

In each case, if the NULL test is necessary, then the dereference should be
moved below the NULL test. I have also taken advantage of the availability
of the value of priv->dev in the subsequent calls to netif_stop_queue and
netif_carrier_off.
