This may just be the rcvif issue where we don't reference count the ifp we
store in rcvif in mbufs?  That was my reaction to your first e-mail except
that you said it wasn't reproducible on some other drivers.  I wonder if
other drivers would also provoke this if you just ran them in a detach/attach
loop long enough.
