information, which is reused when more frames are received.
To fix this, rely on ts->ts_final_idx to select the last attempted rate,
instead of checking whether ts->ts_rate is set.
Additionally, the conversion from the driver rate index back to the
mac80211 rate index can be dropped, as the mac80211 tx status will still
have the original rate index which was used to set up the descriptor.

cfg80211/nl80211: Add userspace authentication flag to mesh setup
During mesh setup, use NL80211_MESH_SETUP_USERSPACE_AUTH flag to create
a secure mesh and route management frames to userspace.
Also, NL80211_CMD_GET_WIPHY now returns a flag NL80211_SUPPORT_MESH_AUTH
if the wiphy's mesh implementation supports routing of mesh auth frames
to userspace. This is useful for forward compatibility between old
kernels and new userspace tools.

ath9k_hw: Fix instable target power control b/w CCK/OFDM
The problem is that when the attenuation is increased,
the rate will start to drop from MCS7 -> MCS6, and finally
will see MCS1 -> CCK_11Mbps. When the rate is changed b/w
CCK and OFDM, it will use register desired_scale to calculate
how much tx gain need to change.
The output power with the same tx gain for CCK and OFDM modulated
signals are different. This difference is constant for AR9280
but not AR9285/AR9271. It has different PA architecture
a constant. So it should be calibrated against this PA

If there are frames already pending in the tx queue, postponing the

Finally, also remove this call from the one place

To prevent this we suck out all pending requests when
