From 870abdf67170daa9f1022e55a35c469239fcc74c Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Sun, 5 Oct 2008 18:04:24 +0200 Subject: mac80211: add multi-rate retry support This patch adjusts the rate control API to allow multi-rate retry if supported by the driver. The ieee80211_hw struct specifies how many alternate rate selections the driver supports. Signed-off-by: Felix Fietkau Signed-off-by: John W.
