-Subject: [PATCH] mac80211: minstrel_ht: fix rounding issue in MCS duration
- calculation
-
-On very high MCS bitrates, the calculated duration of rates that are
-next to each other can be very imprecise, due to the small packet size
-used as reference (1200 bytes).
-This is most visible in VHT80 nss=2 MCS8/9, for which minstrel shows the
-same throughput when the probability is also the same. This leads to a
-bad rate selection for such rates.
-
-Fix this issue by introducing an average A-MPDU size factor into the
-calculation.
