From d34990bbc25559fa1af5e23759c65a3951cbc956 Mon Sep 17 00:00:00 2001 From: Michael Vassernis Date: Mon, 29 Jul 2019 06:01:16 +0000 Subject: [PATCH] cfg80211: fix dfs channels remain DFS_AVAILABLE after ch_switch Depending on the regulatory domain, leaving a DFS channel requires a new CAC to be performed when returning back to that channel. If needed, update dfs states after a driver channel switch.
