From f510bcc21ed97911b811c5bf36ed43a0e94ab702 Mon Sep 17 00:00:00 2001 From: Benjamin Berg Date: Mon, 11 Dec 2023 09:05:28 +0200 Subject: [PATCH] wifi: cfg80211: consume both probe response and beacon IEs When doing a channel switch, cfg80211_update_known_bss may be called with a BSS where both proberesp_ies and beacon_ies is set. If that happens, both need to be consumed.
