From f6c57bafcdebed4429cdda206149ddcbb1d46e91 Mon Sep 17 00:00:00 2001 From: Bruce Allan <bruce.w.allan@intel.com> Date: Thu, 18 Jan 2007 09:25:28 -0800 Subject: [PATCH] e1000: clear ip csum info from context descriptor Since the driver sets the IP checksum insertion bit (IXSM in Status field) in transmit context descriptors, it should clear the IP checksum bits of any garbage so as not to confuse the hardware.
