69e2a77170 carl9170: Remove redundant protection check
The carl9170_op_ampdu_action() function is used only by the mac80211
framework.
Since the mac80211 already takes care of checks and properly serializing
calls to the driver's function there is no need for the driver to do the same
thing.

499afaccf6 ath9k: Isolate ath9k_use_chanctx module parameter
This patch ensures that the module parameter "use_chanctx" is
visible only when CONFIG_ATH9K_CHANNEL_CONTEXT is selected.
Also register the channel context callbacks with mac80211 only
when it is explicitly enabled and compile them out of the driver
when CONFIG_ATH9K_CHANNEL_CONTEXT is not selected.

ba1fa3cd61 ath9k_htc: advertise support for TDLS
Based on a quick test with AR9271, TDLS seems to be working fine.

Tests were done with 2 Atheros AR9271 based devices with firmware
1.3 (sha1 8d49f928aa40ac53c729189bff1333cd373a7fb5), associated
with a WAP54G access point. TDLS worked fine both in WPA2 mode and
without encryption. Stations maintained ping flood traffic between
each other and towards the AP without significant losses.

Not tested with AR7010.

TDLS was enabled in earlier patches the same way for other
Atheros drivers:
ath9k (fd6562344d),
and carl9170 (d1f3de71a5).

Currently it can send regulatory domain change notification before any

e2261afd4c mwifiex: fix decimal printf format specifiers prefixed with 0x
The prefix suggests the number should be printed in hex, so use
the %x specifier to do that.

Found by using regex suggested by Joe Perches.

ec76643b00 b43: implement PPR (Power Per Rate) management/API
Broadcom hardware supports auto-adjustment of TX power depending on the
currently used rate. So far all calculations were handled without any
helpers (API) using big arrays and magic offsets.
It seems Broadcom recently decided to clean this up by developing PPR.
Their wlc_ppr.h can be found in open parts of the SDK.
As we plan to implement support for rate-based TX power it makes sense
to also implement our version of PPR as well.
