From 7cc45e98e539ad98d8af57e4126aaac3e6b8f341 Mon Sep 17 00:00:00 2001 From: Sujith Manoharan Date: Sun, 8 Sep 2013 18:19:55 +0300 Subject: [PATCH] ath10k: Calculate correct peer PHY mode for VHT The peer PHY mode for 11ac operation needs to be determined properly based on the channel bandwidth being used. Fix this so that the proper mode is given to the firmware. kvalo: earlier we used 11na-ht20 in STA mode for 11ac AP peer, this patch changes that to 11ac-vht80. I didn't notice any change in throughput in my tests, but nevertheless it's the right thing to do.
