Subject: [PATCH] cfg80211: fix sband iftype data lookup for AP_VLAN
Date:   Thu, 22 Jun 2023 18:05:01 +0200
Message-ID: <20230622160501.40666-1-nbd@nbd.name>

Since AP_VLAN interfaces are not pushed to the driver, the driver should not
be expected to register iftype data for them.
Map them to the regular AP iftype on lookup.
