If a new context is being added in addition to the current one,
then send the ASSIGN event to abort a running scan since
the addition of a context is usually followed by VIF
assignment and further operations.

Finally move the 'offchannel' instance in ath_softc
inside a CONFIG_ATH9K_CHANNEL_CONTEXT cage. The offchannel
usage in ath9k_calculate_iter_data() is closed off with
an ifdef for now, since the state/opmode calculation is
common for both the channel context mode and the normal mode.

The carl9170_op_ampdu_action() function is used only by the mac80211

Add the missing null termination after strncpy().
This isn't actually a buffer overflow in this case since we use
snprintf() appropriately to fill the buffer passed by the caller,
but in the interest of not turning this into a bug down the road,
go ahead and force termination here.

The files ray_cs.h and rayctl.h both contain two thirds of what
appears to be an include guard using the macro name RAYLINK_H (both
lack the #define). Since RAYLINK_H is not defined anywhere, the

different macro names.

add only one TLV.

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).
