Subject: [PATCH 03/16] ath10k: setup rts/frag thresholds upon vdev creation
Date: Fri,  5 Jul 2013 16:15:04 +0300	[thread overview]
Message-ID: <1373030117-18077-4-git-send-email-kvalo@qca.qualcomm.com> (raw)
In-Reply-To: <1373030117-18077-1-git-send-email-kvalo@qca.qualcomm.com>

From: Michal Kazior <michal.kazior@tieto.com>

mac80211 configures rts/frag thresholds per-hw not
per-vif. ath10k FW expects those values to be set
per-vdev (i.e. per-vif).

ath10k should now respect rts/frag thresholds set
before a given interface was brought up.
