From 4a8523a788fb1c80a2f65a5d65fa36db85398397 Mon Sep 17 00:00:00 2001 From: "Ronald G. Minnich rminnich" Date: Tue, 7 Apr 2009 02:18:13 +0000 Subject: This is a bit of an emergency fix for qemu. Ethernet routing has not been working. Given all the limitations of PIRQ routing we keep it simple and just set the IRQ directly. Most BIOSes are doing setup this way anyways, since there are so many errors in PIRQ tables. Signed-off-by: Ronald G.
