   4 Subject: [PATCH] mac80211: util: don't warn on missing sband iftype data
   5
   6 The kernel currently floods the ringbuffer with warnings when adding a
   7 mesh interface for a device not support HE 6GHz modes.
   8
   9 Return without warning in this case, as mesh_add_he_6ghz_cap_ie calls
  10 ieee80211_ie_build_he_6ghz_cap regardless of the supported interface
  11 modes.
