[NET]: Document ->stop() method netdevice semantics.

parent ad87baec
......@@ -82,3 +82,13 @@ Probing guidelines:
1) Any hardware layer address you obtain for your device should
be verified. For example, for ethernet check it with
linux/etherdevice.h:is_valid_ether_addr()
Close/stop guidelines:
1) After the dev->stop routine has been called, the hardware must
not receive or transmit any data. All in flight packets must
be aborted. If necessary, poll or wait for completion of
any reset commands.
2) The dev->stop routine will be called by unregister_netdevice
if device is still UP.
