From 8c7d857c4a4a552d8d3e1b2e24e1864ec2989285 Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Wed, 25 Jul 2012 01:42:36 +0300 Subject: mac80211: don't call mgd_prepare_tx when associated This doesn't make any sense since we are expected to be on the medium or at least to Tx only when we are on the right channel and the AP/GO can hear us. Move the call to mgd_prepare_tx() for deauth to be only done in case we're sending a deauth while not associated.
