From d64cf63e062f6741f80c393f19c9706358489cc7 Mon Sep 17 00:00:00 2001 From: Arik Nemtsov Date: Mon, 7 Nov 2011 23:24:39 +0200 Subject: [PATCH] mac80211: init rate-control for TDLS sta when supp-rates are known Initialize rate control algorithms only when supported rates are known for a TDLS peer sta. Direct Tx between peers is not allowed before the link is enabled. In turn, this only occurs after a change_station() call that sets supported rates.
