Have Atheros AR9280+AR7010 USB stick athn(4). Long ago I tested it with OpenBSD 5.6 in Host AP mode 5GHz band, it does not work as AP but successful in BSS in both supported bands.
On OpenBSD 6.0 situation is different. It is relatively stable in AP mode, but don't work BSS in 2.4GHz band. On OpenBSD 5.6 it works fine in BSS mode. I don't know what happened, but it will be great to have BSS in 5GHz and 2.4GHz working as before. I can test all the code modification if necessary. Denis
