mac80211: init rate-control for TDLS sta when supp-rates are known (d64cf63e) · Commits · 戴 / test

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. Signed-off-by:
