From ba7af2654e3b7b810c750b3c6106f6f20b81cc88 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Sun, 4 Jun 2023 12:11:20 +0300 Subject: [PATCH] wifi: mac80211: recalc min chandef for new STA links When adding a new link to a station, this needs to cause a recalculation of the minimum chandef since otherwise we can have a higher bandwidth station connected on that link than the link is operating at. Do the appropriate recalc.
