From af00148f63af1b537dd86d46ef468da8e54c3678 Mon Sep 17 00:00:00 2001 From: Michal Kazior Date: Mon, 30 Mar 2015 09:51:56 +0300 Subject: [PATCH] ath10k: simplify fixed rate selection Use the existing ieee80211_rate array instead of definining separate one. This gets rid of the ugly 4-index offset when dealing with 5GHz band.
