Few more questions:
1) does it work with h/w encryption support? (enabled by default)
(if 'yes' - I will remove 'hardware crypto enabled' warning).
2) is there rate control support? (wlandebug -i wlan0 rate ; then transmit
something - if it works then AMRR will print it's current status  
periodically)
3) can you test some disabled capabilities? (ad-hoc/AP modes, 11n)
(see r92ce_adj_devcaps() in sys/dev/rtwn/rtl8192c/pci/r92ce_attach.c).
