From 0f1492d923d3ab43dc88f2021927ac21c2894909 Mon Sep 17 00:00:00 2001 From: Rajkumar Manoharan Date: Sat, 10 Dec 2011 18:59:43 +0530 Subject: [PATCH] ath9k: fix max phy rate at rate control init The stations always chooses 1Mbps for all trasmitting frames, whenever the AP is configured to lock the supported rates. As the max phy rate is always set with the 4th from highest phy rate, this assumption might be wrong if we have less than that. Fix that.
