Please add your patchset history here until V6.
That's what cover letter is supposed to have.

Enable TDLS peer buffer STA feature.
QCA6174 firmware(version: WLAN.RM.4.4) support TDLS peer buffer STA,
it reports this capability through wmi service map in wmi service ready
event. Set related parameter in TDLS WMI command to enable this feature.

No, you haven't, at least not comprehensively. Try to enable debugfs.

It would help if you could (build) test your changes :-)

TDLS peer do not need WEP key. Setting WEP key will lead
to TDLS setup failure. Add fix to avoid setting WEP key
for TDLS peer.
