Allow reusing this for formatting of netdev_add arguments into -netdev.
We need to be able to skip the 'type' property as it's used without the
prefix.
Not quite true. In qemu's net/net.c, there is:
QemuOptsList qemu_netdev_opts = {
.name = "netdev",
.implied_opt_name = "type",
.head = QTAILQ_HEAD_INITIALIZER(qemu_netdev_opts.head),
.desc = {
/*
* no elements => accept any params
* validation will happen later
*/
{ /* end of list */ }
},
The handling of .implied_opt_name means that the following two commands
are identical:
qemu-kvm -netdev user,id=net0
qemu-kvm -netdev type=user,id=net0
So you don't have to specifically handle type= specially. That said, I
don't see any problem in adding this special-casing.
Add infrastructure which allows skipping a certainly named property.
Maybe s/certainly/specifically/
