From a174fd88d2b73c1933ea24ed533354d618c7d089 Mon Sep 17 00:00:00 2001 From: Jesse Brandeburg Date: Tue, 29 Nov 2005 19:23:59 -0800 Subject: [PATCH] [PATCH] e1000: fix for dhcp issue Parse outgoing packets in e1000_transfer_dhcp_info as raw packet even if protocol bits are set. pump, for instance causes kernel panic on some systems, if parsed via udp header. Thanks to Derrell Lipman for reporting and testing.
