RESEND [PATCH 3/3] NetXen: Graceful teardown of interface and hardware upon module unload
Resending patch 3/3 only.
These changes allow driver close routine to be called during module unload,
to clean-up buffers and other software resources, flush queues etc. Also,
hardware is reset to pristine state.
