You are looking for adapters with HOSTAP capability [1] according
http://www.freebsd.cz/doc/handbook/network-wireless.html

This report [1] is from old dongle D-Link DWL-G122 running as a client
[2,3] in FreeBSD 11.0 on imx6. I haven't tried, but according [1] it
should be possible to use it with hostap.

JFYI, RT5370 (Tenda W311MI) and RT5592 (TP Link TL-WDN3200) don't work
for me in [4] and report error (below). But both adapters report HOSTAP
capability in Freebsd 10.2 i386

imx6 kernel: run0: firmware RT3071 ver. 0.33 loaded
imx6 wpa_supplicant[2164]: ioctl[SIOCS80211, op=26, val=0,
arg_len=0]: Operation not supported
imx6 wpa_supplicant[2164]: ioctl[SIOCS80211, op=26, val=0,
arg_len=0]: Operation not supported
imx6 wpa_supplicant[2164]: wlan0: CTRL-EVENT-TERMINATING

Just to be sure. You know that USB adapters don't support 11n at the
moment?

HTH. Cheers
