Created attachment 156478 [details] Remove ieee80211_ack_rate() / unused ackrate variables At this moment ieee80211_ack_rate(): - fully duplicates contents of ieee80211_ctl_rate(); - is not used for anything useful; so it can be safely removed. Also, this patch fixes some 'dead assignment' warnings (from scan.freebsd.org)
Hm ,that's odd. ACK and control rates can be different. I'll go look into it some more.
