From 2cfc6fc584a65db87935ca4e4d5e1ad89d5192ee Mon Sep 17 00:00:00 2001 From: Felix Fietkau Date: Wed, 8 Feb 2012 19:17:11 +0100 Subject: [PATCH] mac80211: do not call rate control .tx_status before .rate_init Most rate control implementations assume .get_rate and .tx_status are only called once the per-station data has been fully initialized. minstrel_ht crashes if this assumption is violated.
