Hi,
Short RfC patch series to get the discussion rolling. We really need to
get the nic drivers qdev-ified properly, so qemu stops segfaulting on
'-device $any_nic_here'.
To keep things small simple I've started with the ne2k_isa. All the PCI
nics share the initialization path and thus I can't simply pick a single
one as example and convert it.
The network card can now be created using ...
-device ne2k_isa,mac=00:11:22:33:44:55,vlan=0,irq=3,id=foo
'info qtree' shows ...
[ ... ]
bus: isa.0
type ISA
dev: ne2k_isa, id "foo"
dev-prop: iobase = 0x300
dev-prop: irq = 3
dev-prop: vlan = 1
dev-prop: mac = 00:11:22:33:44:55
[ ... ]
'info network' shows:
[ ... ]
VLAN 1 devices:
foo: model=ne2k_isa,macaddr=00:11:22:33:44:55
The nic initialization code calls qemu_new_vlan_client() with the
vlan specified using the vlan property. Likewise the device cleanup
code should call qemu_del_vlan_client. You don't see that in the
patches though as ISA devices are not hot-pluggable ;)
struct NICInfo is not needed at all here. I hope we can kill it long-term.
This patch series is also available here:
http://git.et.redhat.com/?p=qemu-kraxel.git;a=shortlog;h=refs/heads/nic.v1
You might find it useful to have a look at the qbus patches. Especially
the hotplug patches which add device_add and device_del monitor
commands. The patches are on the qemu-devel list too and also here:

cheers,
Gerd
