From: Felix Fietkau Date: Wed, 8 Feb 2012 18:17:11 +0000 (+0100) Subject: mac80211: do not call rate control .tx_status before .rate_init X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=216c57b214bd621335ff698b475f6db2802502dc;p=openwrt%2Fstaging%2Fblogic.git 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.
