From a9363914a393ac732cac6798d687cba167a99bad Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sat, 9 Nov 2019 17:06:05 +0100 Subject: [PATCH] mac80211: Allow IBSS mode and different beacon intervals ath10k-ct supports the combination to select IBSS (ADHOC) mode and different beacon intervals together. mac80211 does not like this combination, but Ben says this is ok, so remove this check.
