This is a flaw in recently implemented logic to handle Tx traffic
and scan operation simultaneously. We missed to wakeup main thread
to handle Tx traffic if scan is delayed/aborted.
For some cards (SD8797, for example), firmware will send SLEEP event
if there is no activity for 50msec. While handling the SLEEP event,
main thread will be woken up and Tx packet gets sent hence. In worst
case Tx traffic will be delayed for 50msec.
For other cards, such as USB8797, firmware won't send SLEEP event.
So, Tx traffic gets stuck if no other event triggers the wakeup of
main thread.

wl18xx: sane defaults for HT capabilities
Introduce a default set of HT capabilities that are set according to the
number of antennas on the board. Move the HT setting code down to allow
the number of antennas to be set (and optionally overridden) before it.
Remove the "mimo" HT option, since the default mode now enables MIMO is
possible.
Use this opportunity to add a helper function for setting HT
capabilities and reduce the volume of the code a bit.

wlcore: read FW logs from FW memory on watchdog recovery
FW uses a few memory blocks as a buffer to accumulate FW logs before
transmitting them to the host over SDIO. When FW WatchDog recovery
occurs, the last FW traces are still pending in the buffer. Driver is
to read these FW traces whether log mode is continuous or on demand.
FW memory blocks allocated for the log buffer are handled as a link list:
the first 4 bytes in each memory block contain FW address to the next block.
The end of list condition depends on FW log mode:
- on demand: the list is cyclic, the next address is equal to the first address
- continuous: the address is equal to 0x2000000
Log data resides inside FW memory block with offset depending on
logger mode:
- on demand: 4 bytes (address of the next memory block)
- continuous: 4 bytes and Rx Descriptor structure size
Described FW logger API is backward compatible with previous FW versions.

ath9k_hw: fix OFDM weak signal detection handling
Commit "ath9k_hw: improve ANI processing and rx desensitizing parameters"
was unifying some code related to overriding OFDM weak signal detection,
but seems to have gotten some of the original intent wrong, probably
because of a misnamed variable.
The beacon RSSI is only valid in station mode, and the main reason to check
it in ath9k_hw_set_ofdm_nil is to make sure that OFDM weak signal detection
stays enabled if the RSSI is low, even when the OFDM noise immunity entry
is supposed to disable it.
The above commit removed the mode checks and changed the code so that
OFDM weak signal detection would only be changed if the rssi is high, which
is wrong for everything but client mode.
This patch restores the old behavior in a simplified form.

ath9k_hw: remove aniState->noiseFloor
I don't know why somebody decided to keep a cached copy of beacon rssi in a
variable called 'noiseFloor', but the caching is unnecessary and the variable
name is confusing, so let's just get rid of it entirely.

mac80211: use the correct capability info in ieee80211_set_associated()
If an AP is beaconing with different capabilities than the one we get
in the associate response, we were still using the capabilities

the short slot bit set to zero and then we try to connect to it with
long slot. In this case, we would keep using long slot until the next
beacon was received.
Fix this by using the correct capability value when calling
ieee80211_handle_bss_capability(). We were using cbss->capability,

mac80211: initialize sta pointer to avoid false-positive warning
Some compilers (eg. gcc 4.4.1 for ARM) report a false positive warning
in mlme.c:
net/mac80211/mlme.c: In function 'ieee80211_prep_connection':
net/mac80211/mlme.c:3035: warning: 'sta' may be used uninitialized in this function
This is a false positive because the place where 'sta' is used is
inside an if with the same condition of where it is set:
[...]
if (!have_sta) {
sta = sta_info_alloc(sdata, cbss->bssid, GFP_KERNEL);
if (!sta)
return -ENOMEM;
}
[...]
if (!have_sta) {
[...]
sta->sta.supp_rates[cbss->channel->band] = rates;
[...]
For some reason the compiler doesn't understand this and warns.
While this is not a problem in the code itself, we can avoid polluting
the build logs with false positives by setting sta to NULL on
declaration and checking for sta instead of !have_sta in the second if.
