ifconfig wlan0 create causes memory corruption

[Matthew Dillon]

:It's the bcopy() in ether_ifattach_bpf() with the XXX in the comment.
:ifp is expected to be embedded in a struct arpcom, which is not the
:case for the cloned wlan interface.

    Ok, what I will do is adopt the changes FreeBSD made which is
    to hang arpcom off of a pointer in the ifp instead of embedding
    the ifnet in the arpcom.
