[RFC/RFT] minstrel: update stats after processing status

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Johannes Berg <johannes.berg@xxxxxxxxx>

Instead of updating stats before sending a packet,
update them after processing the packet's status.
This makes minstrel in line with minstrel_ht.
