Added such dbg:
printk(KERN_ERR "%d vs %d, %d vs %d\n",
req_rx_nss, have_rx_nss,
req_tx_nss, have_tx_nss);
if (req_rx_nss > have_rx_nss ||
req_tx_nss > have_tx_nss)
return false;
[ 70.243183] ieee80211_verify_sta_eht_mcs_support nss 4 -
(ARRAY_SIZE(req->rx_tx_max_nss))
[ 70.248336] 4 vs 2, 4 vs 2
[ 70.251035] disable EHT due to mcs
[ 70.260724] wlan1: send auth to ....
AP have 4 NSS.
Will dig more ...
