Message-Id: <20170504064230.22058-1-johannes@sipsolutions.net> Date: Thu, 4 May 2017 08:42:30 +0200 From: Johannes Berg <johannes@...solutions.net> To: linux-wireless@...r.kernel.org Cc: Linus Torvalds <torvalds@...ux-foundation.org>, netdev@...r.kernel.org, Johannes Berg <johannes.berg@...el.com> Subject: [PATCH] cfg80211: make RATE_INFO_BW_20 the default From: Johannes Berg <johannes.berg@...el.com> Due to the way I did the RX bitrate conversions in mac80211 with spatch, going setting flags to setting the value, many drivers now don't set the bandwidth value for 20 MHz, since with the flags it wasn't necessary to (there was no 20 MHz flag, only the others.) Rather than go through and try to fix up all the drivers, instead renumber the enum so that 20 MHz, which is the typical bandwidth, actually has the value 0, making those drivers all work again. If VHT was hit used with a driver not reporting it, e.g. iwlmvm, this manifested in hitting the bandwidth warning in cfg80211_calculate_bitrate_vht().
