From: Igor Mitsyanko <[email protected]>
This patchset has a goal to make operational parameters (channel, BW,
HT/VHT capabilities) configuration possible for qtnfmac driver.
It was part of bigger changeset when it was V1, rest are already applied.
Changelist V1->V2:
PATCH 8:
- fix a typo causing initialization of HT capabilities with VHT data.
Igor Mitsyanko (9):
qtnfmac: use per-band HT/VHT info from wireless device
qtnfmac: initialize HT/VHT caps "can override" masks
qtnfmac: get rid of PHYMODE capabilities flags
qtnfmac: extend "IE set" TLV to include frame type info
qtnfmac: SCAN results: retreive frame type information from "IE set"
TLV
qtnfmac: convert "Append IEs" command to QTN_TLV_ID_IE_SET usage
qtnfmac: configure and start AP interface with a single command
qtnfmac: include HTCAP and VHTCAP into config AP command
qtnfmac: pass all CONNECT cmd params to wireless card for processing

"IE set" TLV carries the same information as
qlink_event_scan_result::frame_type. Convert the event to make use of
TLV and drop frame_type member.
While at it, make qlink_event_scan_result structure alignement-safe.

Specifically, following parameters are needed for wireless device
configuration but were not available to it before:
- HT/VHT capabilities and capabilities masks.
- full channel info (not just IEEE number)
- BSSID hint
- previous BSSID for reassoc request
Move Management Frame Protection setting from common encr info
structure into STA-specific .connect command parameters.
Make sure that all new qlink structure definitions are alignment-safe.

From: Igor Mitsyanko <[email protected]>
HT/VHT capabilities must be reported per each band supported by a radio,
not for all bands on a radio. Furthermore, driver better not assume
any capabilities and just use whetever is reported by device itself.
To support this, convert "get channels" command into "get band info"
command. Difference is that it may also carry HT/VHT capabilities along
with channels information.
While at it, also add "num_bitrates" field to "get band info" command,
for future use.

- generic interface configuration (security, channel etc)
- IE's processing
- enable AP mode on interface
This separation would not allow to do a proper device configuration as
first stage needs to use information from IEs that are processed on
a second stage. Which means first and second stages have to be meged.
In that case there is no point anymore to keep third stage either, so
merge all three into a single command.
This new command carries all the same info as contained in
"struct cfg80211_ap_settings".

I'm having a hard time to believe that this in hotpath so the use of
unlikely() is not really making any sense to me. No need to resend
because of this, just looks strange and makes the code harder to read.
