Subject: [PATCH] fix MCA when shutting down tulip quad-NIC

From: andrew.patterson@...com

 https://bugzilla.novell.com/show_bug.cgi?id=SUSE39204

Shutting down the network causes an MCA because of an IO TLB error when
a DEC quad 10/100 card is in any slot.  This problem was originally seen
on an HP rx4640.

Andrew: Why is it tp->pdev instead of pdev?
