From 4926b51bfaa6d36bd6f398fb7698679d3962e19d Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 6 Feb 2019 13:17:12 +0200 Subject: [PATCH] mac80211: call drv_ibss_join() on restart If a driver does any significant activity in its ibss_join method, then it will very well expect that to be called during restart, before any stations are added. Do that.
