6010e72cdf ath9k: merge power correction constants
The existing constants are used for reduction/increase
tx power level on devices with 2x2 and 3x3 chainmask.

Both reduction and increase must use the same value, so
it makes no sense to use separate constants for them.

0479c19d9f iwlwifi: remove uCode alternatives mechanism
We've never released firmware using the alternatives
mechanism and our build process makes that difficult
anyway. This means that in every file we have ever
built (except maybe by hand for testing) the listed
alternative was 0. Make the alternative field in the
TLVs part of the TLV number (thus expanding that to
32 bits); this gives us more TLV numbers (not really
needed) and more importantly protects against rogue
firmware files that actually do use the alternatives
mechanism -- those will now be rejected since they
don't contain any valid TLVs.

84965795b2 iwlwifi: remove no_sleep_autoadjust
My original idea with this was to adjust the sleep
pattern of the uCode based on the maximum network
latency userspace asked for. Due to nobody wanting
to test it, this logic was disabled by default. It
seems the time has come to remove it, since it's
not only always disabled but there also don't seem
to be any applications that actually request a max
network latency.

bb3e10fb58 mac80211: check IEEE80211_HW_QUEUE_CONTROL in ieee80211_check_queues()
Commit 3a25a8c8 (mac80211: add improved HW queue control) introduced a
bug when running in AP mode without the IEEE80211_HW_QUEUE_CONTROL
flag set.  The ieee80211_check_queues() function always returns
-EINVAL, preventing AP mode from starting.  To fix this, check whether
this flag is set before checking if cab_queue is set properly.

8e8b41f9d8 cfg80211: enforce lack of interface combinations
My grand plan to allow drivers to gradually move over
to advertising virtual interface combinations and only
enforce with drivers that do want it enforced doesn't
seem to be working out, only Christian ever added the
advertising (to carl9170), nobody else did.

Begin enforcing combinations in cfg80211 so that users
can rely on the information reported about a device.

94a2ca311c brcm80211: smac: only provide valid regulatory hint
The driver provides a regulatory hint to cfg80211 as obtained from the
SPROM. Mostly, this will be a two-letter ISO country code. However, it
may obtain special country code similar to the world regulatory domain
as used in cfg80211. This patch avoids setting these special codes as
the hint is lost to cfg80211.
