From 586e01ededf9b713a1512dd658806791a7ca1a50 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 14 Feb 2013 12:13:53 +0100 Subject: [PATCH] mac80211: prevent spurious HT/VHT downgrade message Even when connecting to an AP that doesn't support VHT, and even when the local device doesn't support it either, the downgrade message gets printed. Suppress the message if HT and/or VHT is disabled.
