    IAPP initialization failed when i tried to bring up the hostapd
with IAPP support(all these i didn`t test IAPP), and i guess the
problem is "setsockopt[UDP,IP_ADD_MEMBERSHIP]: No such device", How to
resolve this issue??
I am using hostap-0.3.7 and madwifi-bsd latest. and my OS is Montavista 3.0.
I`m appending log here.
Thanx in advance,
