From db6d1e942f5a2828e1245e16ceb997f537a2d1a4 Mon Sep 17 00:00:00 2001 From: David Bauer Date: Sat, 25 Jul 2020 01:43:26 +0200 Subject: [PATCH] mac80211: util: don't warn on missing sband iftype data The kernel currently floods the ringbuffer with warnings when adding a mesh interface for a device not support HE 6GHz modes. Return without warning in this case, as mesh_add_he_6ghz_cap_ie calls ieee80211_ie_build_he_6ghz_cap regardless of the supported interface modes.
