From 6ec288a178de37c30831398f5a470fdc43b18130 Mon Sep 17 00:00:00 2001 From: David Bauer Date: Sat, 14 Dec 2019 23:38:02 +0100 Subject: [PATCH] mac80211: fix txpower when using DFS channels With this patch, txpower for the PHY is applied when configuring the PHY instead of the VIF. Otherwise, the configured txpower is not applied for the first initialized VIF when using DFS channels, as it is currently applied too early when the CAC hasn't finished.
