From 5db4c4b9559f8cddd5f7f74e58c7b8f172120e6d Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Tue, 23 Jul 2019 21:00:01 +0300 Subject: [PATCH] mac80211: pass the vif to cancel_remain_on_channel This low level driver can find it useful to get the vif when a remain on channel session is cancelled. iwlwifi will need this soon.
