From d658df243d3e997468bdf78cd03ebe44151973d5 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 27 Jun 2022 12:36:03 +0200 Subject: [PATCH] wifi: cfg80211: handle IBSS in channel switch commit 77e7b6ba78edf817bddfa97fadb15a971992b1ee upstream. Prior to commit 7b0a0e3c3a88 ("wifi: cfg80211: do some rework towards MLO link APIs") the interface type didn't really matter here, but now we need to handle all of the possible cases. Add IBSS ("ADHOC") and handle it.
