iwlwifi: reduce sta_lock hold time in TX
When we TX, we hold the sta_lock for a long
time, a lot of which isn't needed. Reduce
the time we hold the lock. Note that this
doesn't really change anything as the code
is already under the other spinlock, but it
makes the code easier to read.

iwlwifi: always monitor for stuck queues
If we only monitor while associated, the following
can happen:
- we're associated, and the queue stuck check
runs, setting the queue "touch" time to X
- we disassociate, stopping the monitoring,
which leaves the time set to X
- almost 2s later, we associate, and enqueue
a frame
- before the frame is transmitted, we monitor
for stuck queues, and find the time set to
X, although it is now later than X + 2000ms,
so we decide that the queue is stuck and
erroneously restart the device
It happens more with P2P because there we can
go between associated/unassociated frequently.

mwifiex: fix bug in wildcard scan handling
Currently if valid SSID list is provided in scan request, driver
performs specific SSID scan otherwise wildcard scan is chosen.
When wpa_supplicant provides valid SSID list followed by
zero-length SSID for wildcard scan, only specific SSID scan is
performed by driver. Actually driver is expected to do both type
of scanning in this case. The patch fixes this issue.
Also, use SSID list pointer provided by stack directly, instead
of copying SSID's to local structure.

mwifiex: correct bitrates advertised to cfg80211
1. Driver and firmware do not support 22Mbps and 72Mbps bitrates.
Remove them from the rate table advertised to cfg80211.
2. First 4 rates from mwifiex_rates table are not valid for
5GHz/A band. Set correct bitrate array's index and no of rates for
ieee80211_supported_band for 5GHz band.

Move the sprom parsing from nvram into sprom.c. There are all values

bcma: add support for sprom not found on the device
On SoCs the sprom is stored in the nvram in a special partition on the

sometimes also for a pci devices using bcma. This patch makes it
possible for the arch code to register a function to fetch the needed
