ieee80211_waitfor_parent hangs forever

[Farhan Khan]

Hi all,

I traced back where my driver-in-development hangs when I issue "ifconfig
wlan0 up", and it hangs on ieee80211_waitfor_parent(), specifically:

ieee80211_draintask(ic, &ic->ic_parent_task);

Reference:
http://src.illumos.org/source/xref/freebsd-head/sys/net80211/ieee80211_proto.c#1406

I am not familiar with the source just yet, What does this function do?
And, what is ic_parent_task?

It appears that Andriy reported this same issue here:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=208860 but I did not see
a resolution.

Thanks!
