From 1431fcb74eb5c67d3c38db5e5fe60b726c204273 Mon Sep 17 00:00:00 2001 From: Andrei Otcheretianski Date: Mon, 14 Oct 2013 10:46:55 +0200 Subject: [PATCH] mac80211: fix honouring rate flags in low-rate transmit Transmissions with the IEEE80211_TX_CTL_NO_CCK_RATE flag set (which can come from userspace) were no longer guaranteed to be transmitted with allowed rates since commit 2103dec14792b ("mac80211: select and adjust bitrates according to channel mode") due to a missing rate_flags check in that commit. The commit also introduced the need to check the 5/10 MHz flags but accidentally didn't. Fix it by adding the missing check.
