Commit Message

Adding bss-color configuration for HE mode alone.
Earlier we have enabled it by default, irrespective
of capabilities. But bss-color feature is only for
HE mode. Hence avoiding this by adding bss-color flag
only for HE mode.

Fixes: eb024f1abca3("mac80211: avoid bss color setting in non-he mode")
Reported-by: kernel test robot <lkp@intel.com>
Reported-by: Rajkumar Manoharan <rmanohar@codeaurora.org>
Signed-off-by: P Praneesh <ppranees@codeaurora.org>
---
v3:
	-fixed compilation error, reported by kernel test robot.
v2:
	-addressed Rajkumar's comments.
	-moved remaining HE flags under
	 corresponding check.
