From ee0e16ab756ac060afe367199bc36db26a157444 Mon Sep 17 00:00:00 2001 From: Peter Seiderer Date: Sat, 2 Apr 2022 17:30:14 +0200 Subject: [PATCH] mac80211: minstrel_ht: fill all requested rates Fill all requested rates (in case of ath9k 4 rate slots are available, so fill all 4 instead of only 3), improves throughput in noisy environment.
