261 	 *	signals along the MII serial bus.  These operations are

263 	 *	faster operations (e.g. interrupts) aren't delayed by
264 	 *	waiting for it.
265 	 *
266 	 * <oplock> is a general "outer" lock, protecting most r/w data
267 	 *	and chip state.  It is also acquired by the interrupt
268 	 *	handler.
269 	 *
270 	 * <rxlock> is used to protect the Rx-side buffers, descriptors,
271 	 *	and statistics during a single call to dmfe_getp().
272 	 *	This is called from inside the interrupt handler, but
273 	 *	<oplock> is not held across this call.
274 	 *
275 	 * <txlock> is an "inner" lock, and protects only the Tx-side
276 	 *	data below and in the ring buffers/descriptors.  The
277 	 *	Tx-side code uses only this lock, avoiding contention
278 	 *	with the receive-side code.
279 	 *
280 	 * Any of the locks can be acquired singly, but where multiple
281 	 * locks are acquired, they *must* be in the order:
282 	 *
283 	 *	milock >>> oplock >>> rxlock >>> txlock.
284 	 *
285 	 * *None* of these locks may be held across calls out to the
286 	 * MAC routines mac_rx() or mac_tx_notify(); MAC locks must
287 	 * be regarded as *outermost* locks in all cases, as they will
288 	 * already be held before calling the ioctl() or get_stats()
289 	 * entry points - which then have to acquire multiple locks, in
290 	 * the order described here.
