I have two wireless nics on same host, I show two answers:
[root@pavilion /usr/home/laa]# ifconfig ral0 list caps
ral0=2181e500<IBSS,HOSTAP,TXPMGT,SHSLOT,SHPREAMBLE,MONITOR,WPA1,WPA2,BGSCAN>
[root@pavilion /usr/home/laa]# ifconfig rum0 list caps
rum0=2181e500<IBSS,HOSTAP,TXPMGT,SHSLOT,SHPREAMBLE,MONITOR,WPA1,WPA2,BGSCAN>
[root@pavilion /usr/home/laa]#

Yes, it shows, but adhoc mode does not work with wi0 from FreeBSD 4.11

My ral0 card is Linksys WMP54G, my rum0 card is
rum0: <Ralink 802.11 bg WLAN, class 0/0, rev 2.00/0.01, addr 3> on uhub1
Both cant work with wi0 card from FreeBSD 4.11.
Please, help me to create adhoc network with any of wi0 (4.11), ral0 and
rum0 on 7.0-STABLE.
Thank you very much, Sam!!!
