Subject: [PATCH] wifi: mac80211: fix MLO + AP_VLAN check
Date: Wed, 14 Dec 2022 14:03:26 +0100 [thread overview]
Message-ID: <20221214130326.37756-1-nbd@nbd.name> (raw)
Instead of preventing adding AP_VLAN to MLO enabled APs, this check was
preventing adding more than one 4-addr AP_VLAN regardless of the MLO status.
Fix this by adding missing extra checks.
Fixes: ae960ee90bb1 ("wifi: mac80211: prevent VLANs on MLDs")
