Subject: [PATCH] wifi: cfg80211: Allow action frames to be transmitted with link BSS in MLD
Date: Wed, 1 Feb 2023 11:46:02 +0530	[thread overview]
Message-ID: <> (raw)

Currently action frames TX only with ML address as A3(BSSID) are
allowed in an ML AP, but TX for a non-ML Station can happen in any
link of an ML BSS with link BSS address as A3.
In case of an MLD, if User-space has provided a valid link_id in
action frame TX request, allow transmission of the frame in that link.
