From 4a21a8ae7964278f6ed8168a4391eaa88c4ab452 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 12 Jul 2022 11:33:57 +0200 Subject: [PATCH] wifi: mac80211: mlme: change flags in ieee80211_determine_chantype() For MLO we'll need to read flags not directly from the link as it may not even exist yet if we're just setting up flags for a secondary link before sending the association request, so pass the incoming conn_flags separately. Also, while at it, pass the sdata/link separately as for non-tracking now the link may be NULL.
