014cf3bb1e ath9k: disable beaconing before stopping beacon queue
Beaconing should be disabled before stopping beacon queue.
Not doing so could queue up beacons in hw that causes
failure to stop Tx DMA, due to pending frames in hw
and also unnecessary beacon tasklet schedule.

d76dfc612b rt2x00: Check for errors from skb_pad() calls
Commit 739fd94 ("rt2x00: Pad beacon to multiple of 32 bits")
added calls to skb_pad() without checking the return value,
which could cause problems if any of those calls does happen
to fail. Add checks to prevent this from happening.

642745184f Bluetooth: Merge L2CAP and SCO modules into bluetooth.ko
Actually doesn't make sense have these modules built separately.
The L2CAP layer is needed by almost all Bluetooth protocols and profiles.
There isn't any real use case without having L2CAP loaded.
SCO is only essential for Audio transfers, but it is so small that we can
have it loaded always in bluetooth.ko without problems.
If you really doesn't want it you can disable SCO in the kernel config.

c91d01556f iwl3945: remove plcp check
Patch fixes:
https://bugzilla.redhat.com/show_bug.cgi?id=654599

Many users report very low speed problem on 3945 devices,
this patch fixes problem, but only for some of them.

For unknown reason, sometimes after hw scanning, device is not able
to receive frames at high rate. Since plcp health check may request
hw scan to "reset radio", performance problem start to be observable
after update kernel to .35, where plcp check was introduced.

Bug reporter confirmed that removing plcp check fixed problem for him.
