There was a deadlock when rfkill-blocking a wireless interface,
because we were locking the rdev mutex on NETDEV_GOING_DOWN to stop
sched_scans that were eventually running. The rfkill block code was
already holding a mutex under rdev:
kernel: =======================================================
kernel: [ INFO: possible circular locking dependency detected ]
kernel: 3.0.0-rc1-00049-g1fa7b6a #57
kernel: -------------------------------------------------------
kernel: kworker/0:1/4525 is trying to acquire lock:
kernel: (&rdev->mtx){+.+.+.}, at: [<ffffffff8164c831>] cfg80211_netdev_notifier_call+0x131/0x5b0
kernel:
kernel: but task is already holding lock:
kernel: (&rdev->devlist_mtx){+.+.+.}, at: [<ffffffff8164dcef>] cfg80211_rfkill_set_block+0x4f/0xa0
kernel:
kernel: which lock already depends on the new lock.
To fix this, add a new mutex specifically for sched_scan, to protect
the sched_scan_req element in the rdev struct, instead of using the
global rdev mutex.

Each AC is stopped when its queue is filled up to the high watermark,
and restarted when its queue it lower than the low watermark. This
ensures congested ACs are not able to starve other ACs.

The current TX watermark settings cause the driver to stop queues too
frequently. Among other things, this can have a negative impact on WMM
prioritization, since mac80211 sorts pending packets by their ACs.
Fix this by increasing the high watermark to 256 packets. Increase the
low watermark to 32 to minimize periods with queues being stopped.

When selecting packets for transmission, prefer the ACs that are least
occupied in the FW. When packets for multiple ACs are present in the FW,
it decides which to transmit according to WMM QoS parameters.
With these changes, lower priority ACs should not be starved when higher
priority traffic is present.

When operating with TKIP encryption, the function wl1271_tx_fill_hdr()
relocates the 802.11 header to the start of the frame, and leaves room
for the security header.
Some functions in the Tx path rely on the location of the header,
namely, for purposes of roaming in STA mode and connecting new stations
in AP mode. Call these functions only after the header is relocated.

In AP mode we register for the MAX_TX_RETRY and INACTIVE_STA events.
Both are reported to the upper layers as a TX failure in the offending

Do not reset the security sequence number when issuing a join command or
interface is removed. Instead, reset the counter only during the unjoin
command.
Added the notion of counter wrap-around to the LSB number in
wl1271_tx_complete_packet.
Added post recovery padding to adjust for potential security number
progress during the recovery process by the firmware and avoid
potential interop issues in encrypted networks.

This patch fixes the freescale spi driver for CPM. Without this
patch SPI on CPM failed because cpm_muram_alloc_fixed tries to
allocate muram in an preserved area. The error reported was:
mpc8xxx_spi f0011a80.spi: can't allocate spi parameter ram
mpc8xxx_spi: probe of f0011a80.spi failed with error -12
Now the driver uses of_iomap to get access to this area
similar to i2c driver driver in the i2c-cpm.c which has a
similar device tree node. This is tested on a MPC8247 with CPM2.
