Subject: [PATCH] forcedeth: msi interrupts
Date: Friday, June 6, 2008 - 2:03 pm

This patch adds a workaround for lost MSI interrupts. There is a race
condition in the HW in which future interrupts could be missed. The
workaround is to toggle the MSI irq mask.

Added cleanup based on comments from Andrew Morton.
