[PATCH] mac80211: Send EAPOL frames at lowest rate

2015-02-26 Thread Jouni Malinen
The current minstrel_ht rate control behavior is somewhat optimistic in trying to find optimum TX rate. While this is usually fine for normal Data frames, there are cases where a more conservative set of retry parameters would be beneficial to make the connection more robust. EAPOL frames are
