Subject: [PATCH] wifi: mac80211:  Improve bss-color configuration.
Date: Thu,  7 Mar 2024 10:10:39 -0800
Message-ID: <20240307181039.3219840-1-greearb@candelatech.com>

From: Ben Greear <greearb@candelatech.com>

Always tell driver to apply bss color settings if beacon indicates
the bss coloring has been set.

And only enable bss coloring if beacon indicates bss color setting
is valid and also enabled.
