Hi,
It's been a long time since that fix was developed.

At this point it would be necessary to debug the problem from scratch.
I don't have time to work on this in the near future, sorry.

Maybe someone else wants to figure out what is wrong.

Title:
  emulated netcards don't work with recent sunos kernel

Status in QEMU:
  New

Bug description:
  hi there,

  i'm using qemu-kvm backend in version: # qemu-kvm -version
  QEMU PC emulator version 0.12.5 (qemu-kvm-0.12.5), Copyright (c) 2003-2008 Fabrice Bellard

  and there are just *not working any of model=$type with combinations
  of recent sunos (solaris, openindiana, opensolaris, ..) ..

  you can download for testing purposes iso from here: http://dlc-
  origin.openindiana.org/isos/147/ or from here:
  http://genunix.org/distributions/indiana/ << osol and oi are also
  bubuntu-like *live cds, so no need to bother with installing

  behaviour is as follows:
  e1000 - receiving doesn't work, transmitting works .. dladm (tool for handle ethers) shows that is all ok, correct mode is loaded up, it just seems like this driver works at 100% but ..

  rtl8169|pcnet - works in 10Mbit mode with several other issues like
  high cpu utilization and so .. dladm is unable to recognize options
  for this kind of -nic

  others - just don't work

  .. i experienced this issue several times in past .. woraround was,
  that rtl8169 worked so-so .. with recent sunos kernel it doesn't.

  it's easy to reproduce, this is why i'm not putting here more then
  launching script for my virtual machine:

  # cat openindiana.sh
  qemu-kvm -hda /home/kvm/openindiana/openindiana.img -m 2048 -localtime -cdrom /home/kvm/+images/oi-dev-147-x86.iso -boot d \
  -vga std -vnc :9 -k en-us -monitor unix:/home/kvm/openindiana/instance,server,nowait \
  -net nic,model=e1000,vlan=1 -net tap,ifname=oi0,script=no,vlan=1 &

  sleep 2;
  ip l set oi0 up;
  ip a a 192.168.99.9/24 dev oi0;
