mac80211: fix probe response wait timing
In "mac80211: split out and decrease probe wait time" I tried
to reduce the time waiting for a probe response, but failed to

The PCDAC steps come from the EEPROM and should never be equal, but
we should gracefully handle that case, so warn and bail out.

cfg80211: fix in nl80211_set_reg()
There is a race on access to last_request and its alpha2
through reg_is_valid_request() and us possibly processing
first another regulatory request on another CPU. We avoid
this improbably race by locking with the cfg80211_mutex as
we should have done in the first place. While at it add
the assert on locking on reg_is_valid_request().

This has no functional change except we save a kfree(rd) and
allows us to clean this code up a bit after this. We do
avoid an unnecessary kfree(NULL) but calling that was OK too.

ath9k: Move PS wakeup/restore calls from isr to tasklet
We do not need to do this in ath_isr() and it looks like the modified
version ends up being more stable as far as being able receive beacon
frames is concerned. Furthermore, this reduces need to move between
AWAKE and NETWORK SLEEP states when processing some unrelated
interrupts.

cfg80211: allow wext to remove keys that don't exist
Some applications using wireless extensions expect to be able to
remove a key that doesn't exist. One example is wpa_supplicant
which doesn't actually change behaviour when running into an
error while trying to do that, but it prints an error message
which users interpret as wpa_supplicant having problems.
The safe thing to do is not change the behaviour of wireless
extensions any more, so when the driver reports -ENOENT let
the wext bridge code return success to userspace. To guarantee
this, also document that drivers should return -ENOENT when the
key doesn't exist.

mac80211_hwsim: Group radios
Currently all radios receive all traffic on the simulated air
if they are tuned to the same channel. This patch introduces
the concept of grouping, which allows to assign a radio to
certain group. Only radios in the same group can 'see' each other.
Each bit in /debug/ieee80211/phy*/hwsim/group
represents one group. By default all radios belong to the same group "1",
e.g. bit 1 is set. Additionally a radio can belong to several groups.
