libertas: handle command failure immediately
Fail commands immediately when the request cannot be sent to the hardware.
This solves the following deadlock:
1. Two commands are in the queue.
2. The first command is sent, but causes a timeout, which kicks off an
asynchronous device reset
3. The second command is submitted to the device, and fails. The failure
is noted but the existing code waits for the timeout handler to take
care of the failure.
4. The device reset kicks in, causing the device "surprise removed" flag
to be set as the device disappears from the bus.
5. lbs_thread notes this and enters "adapter removed; waiting to die"
mode, without processing any further command timeouts.
While adjusting lbs thread logic to handle this situation may be one way
to fix this, it seems more practical to simplify handling of host_to_card
failure so that the commands are failed immediately without waiting for
more compliated timeout logic to kick in.

rtlwifi: rtl8192de: Fix phy-based version calculation
Commit
d83579e2a50ac68389e6b4c58b845c702cf37516 incorporated some
changes from the vendor driver that made it newly important that the
calculated hardware version correctly include the CHIP_92D bit, as all
of the IS_92D_* macros were changed to depend on it. However, this bit
was being unset for dual-mac, dual-phy devices. The vendor driver
behavior was modified to not do this, but unfortunately this change was
not picked up along with the others. This caused scanning in the 2.4GHz
band to be broken, and possibly other bugs as well.
This patch brings the version calculation logic in parity with the
vendor driver in this regard, and in doing so fixes the regression.
However, the version calculation code in general continues to be largely
incoherent and messy, and needs to be cleaned up.

cfg80211: fix set_regdom() to cancel requests with same alpha2
While adding regulatory support to ath6kl I noticed that I easily
got the regulatory code confused. The way to reproduce the bug was:
1. iw reg set FI (in userspace)
2. cfg80211 calls ath6kl_reg_notify(FI)
3. ath6kl sets regdomain in firmware
4. firmware sends regdomain event to notify about the new regdomain (FI)
5. ath6kl calls regulatory_hint(FI)
And this (from FI to FI transition) confuses cfg80211 and after that I
only get "Pending regulatory request, waiting for it to be
processed...." messages and regdomain changes won't work anymore.
The reason why ath6kl calls regulatory_hint() is that firmware can change
the regulatory domain by it's own, for example due to 11d IEs. I could
of course workaround this in ath6kl but I think it's better to handle
the case in cfg80211.
The fix is pretty simple, use a different error code if the regdomain is
same and then just set the request processed so that it doesn't block new
requests.

brcmsmac: restructure info->control.sta handling as it is goning to be removed soon.
brcmsmac uses info->control.sta while doing ampdu aggregation. This patch
changes the usage of the structure info->control.sta, as it is going to be
removed soon from struct ieee80211_tx_info. This patch is a pre-requisit in
order to add transmission power control (TPC) to the mac80211 subsystem.

mac80211: add time synchronisation with BSS for assoc
Some drivers (iwlegacy, iwlwifi and rt2x00) today use the
bss_conf.last_tsf value. By itself though that value is
completely worthless since it may be ancient. What really
is needed is synchronisation between some device time and
the TSF.
To clarify this, rename bss_conf.last_tsf to sync_tsf and
add sync_device_ts which is obtained from rx_status which
gets a new field device_timestamp for this purpose. This
is intentionally not using the mactime field since that
is used for other things and in IBSS is expected to sync
with the IBSS's TSF which isn't necessarily true for the
device timestamp.
Also, since we have the information and it's useful even
before the connection has been established, give all the
timing details to the driver before authenticating.

brcmsmac: extend brcms_c_chipmatch() to also handle non PCIe devices
Now brcms_c_chipmatch() is also able to handle non PCI devices and also
does some checking for SoC if they are supported by brcmsmac.

brcmsmac: fix DMA on SoCs
These extra offsets are only needed by PCIe devices and not when
running on an SoC.

brcmsmac: extend xmtfifo_sz array
The xmtfifo_sz array contains the queue sizes for the different core
revs. This array missed the sizes for the core rev 17 and 28. This
patch extends the array to also include these sizes and adds a warning
if no queue size is stored in the array for the given core rev.
