Question about two option formats for netdev

[Masahiro Yamada]

Hi.

I have a question about adding
a network device.


qemu-system-arm -machine vexpress-a9 \
-net nic,model=lan9118 -net user   ...

works for me, but 'man qemu-system-arm'
says this is "Legacy option".


Is there any new (or recommended) form
to use a lan9118 device?


If I understand correctly,

-netdev user,id=<id>   \
-device <driver>,netdev=<id>

is the new option form.

For example, I can use the new form
for virtio-net-device.


But, it does not work for lan9118,
and actually I cannot see lan9118 in
"qemu-system-arm -machine vexpress-a9 -device help".


So, the two options are different worlds,
we need to choose appropriate form
to use a particular device, correct?
