Title:
  e1000 - no link detected by VXWorks based guest

Status in QEMU:
  Expired

Bug description:
  I'm trying to get a VXWorks image running inside a qemu guest.  I have
  the machine running, however, the vxworks image only has support for
  the 82544EI device so I had to change the device ID in e1000.c to get
  the device even recognized so I'm not sure if this is a bug or an
  issue for the development list.

  
  After changing e1000.c, the device is now seen by the guest OS, however, it 
never gets a link.  I've attached the e1000 debug logs in the hopes that 
someone can help me understand where to start looking into why this guest won't 
get a link.

  I tested the updated e1000 driver with a debian live CD and the card
  works under it, so it doesn't appear that the issue is with the driver
  string change but rather something in the e1000 driver itself.

  Here is the command I'm using to start QEMU:

  /opt/qemu/bin/qemu-system-i386  -cpu coreduo -hda /root/vxworks_test
  -m 2048 -netdev tap,ifname=tap0,id=net0 -netdev
  tap,ifname=tap1,id=net1 -device
  e1000,netdev=net0,mac=00:00:e8:01:02:03 -device
  e1000,netdev=net1,mac=00:00:e8:01:02:04 -boot c -curses -no-kvm -D
  /tmp/qemu.log 2>/tmp/e1000.log
