Since vge(4) uses MTX_RECURSE mutex and miibus(4) handler is
protected with the mutex I guess it wouldn't help much.
I guess it needs a seperate mutex to protect miibus(4) handler
and should remove the use of MTX_RECURSE. vge(4) also has a bug
if mbuf chain is too long(7 or higher) and defragmentation with
m_defrag(9) fails it would access an invalid mbuf chain.
All these requires lots of work and need a real hardware.
Oleg, if you have hardware, would you fix it?
