| <li>Repaired the 'ifconfig nwflag' command (broken since OpenBSD 6.4). | |||
| <li>Added a new 'stayauth' nwflag which can be set to ignore deauth frames. | |||
| This is useful when deauth frames are being spoofed by an attacker. | |||
| <li>Repaired the 'ifconfig mode' command to properly force a wireless | |||
| interface into 11a/b/g/n mode. | |||
| <li>Made 11n Tx rate selection more sensitive to transmission failures. | |||
| <li>Fixed automatic use of HT protection in 11n hostap mode. | |||
| <li>Fixed WPA APs occasionally appearing as non-WPA APs during AP selection. | |||
| <li>Fixed some eligible APs being ignored during AP selection after a | |||
| roaming failure. | |||
| <li>Added support for 802.11n Tx aggregation to net80211 and the | |||
