[ath9k-devel] [PATCH 4/4] ath10k: do not setup rts/frag thresholds for suspended interfaces

mac80211 calls for rts/frag threshold hooks before any interface is brought back up again when resuming. We would set vdev parameters before given vdev is created lading to a FW crash. rts/frag thresholds will be re-set accordingly in add_interface() hook anyway. Signed-off-by: Michal Kazior
