Subject: [PATCH 1/3] ath10k: Add ath10k-ct firmware feature flags and descriptions.

From: Ben Greear <[email protected]>

These feature flags are used by ath10k-ct firmware. Add these
so we can use them in future patches and so there are no warings
about feature flags on loading ath10k-ct firmware.

Subject: [PATCH 3/3] ath10k: Support survey dump for ath10k-ct 10.1 firmware.

From: Ben Greear <[email protected]>

Recent ath10k-ct 10.1 firmware supports survey results, and
advertises the appropriate service flags. This confuses
the ath10k driver because the 10.1 wmi commands are not set up
for survey information. So, this patch adds support for
handling survey information. Example output:

Survey data from wlan0
frequency: 5180 MHz [in use]
noise: -97 dBm
channel active time: 44 ms
channel busy time: 15 ms
channel receive time: 7 ms
channel transmit time: 7 ms
Survey data from wlan0
frequency: 5200 MHz
noise: -98 dBm
channel active time: 46 ms
channel busy time: 2 ms
...

Subject: [PATCH 2/3] ath10k: Don't try un-supported idle_ps_config command.

From: Ben Greear <[email protected]>

The warning the the logs does not give user a clue as to what
command is failing, so it is worth it to check for un-supported
command before trying the call.

And add return-code to survey error message.
