Hi,all

Based on Freebsd8.0,the multicast frames are transmited at a fixed rate 1Mbps. I want to change the fixed rate to self-adaptive rate like unicast. 

I change the multicast path to unicast in if_ath.c of ath code,but still fail.Should I change the rate control algorithm? What changes I must do? Can you give me some advise,ideas? 

 

Thanks!
