From e4135c2da11c337e3759f98727c4819ba2a849fa Mon Sep 17 00:00:00 2001 From: Dhananjay Phadke Date: Fri, 17 Jul 2009 15:27:08 +0000 Subject: netxen: fix thermal check and shutdown Check temperature for all PCI functions, that can allow graceful shutdown of all interfaces on the overheated card. Old code was only monitoring temperature for function 0 only. Signed-off-by: Dhananjay Phadke Signed-off-by: David S.
