The performance drop is about 100Mbps+ Our setup is a hostap (2.10) configured AP on 802.11ac, channel 46. (40MHz). The client connects via wpa (2.10) and then we produce traffic. Before this commit, the throughput was around 250 Mbps, with this commit the performance is now down to 135 Mbps. The wifi cards we use are WLE600VX from compex, a ath10k based one. The kernel we're on is 6.1.80. We've seen it on 6.6 too but didn't investigate. Now, the ieee80211_sta_set_rx_nss() function has two FIXME comments. One in where it handles the ht capability and one in the vht part. Both FIXME's are: 'consider rx_highest?'I think you'll find that all that is unrelated, and this fixes it:
