[Qemu-devel] [PATCH 3/4] net.h: Add description fields for qdev properites

[Amit Shah <amit.shah@redhat.com>]

This results in an output like:

$ ./x86_64-softmmu/qemu-system-x86_64 -device virtio-net-pci,?

...

virtio-net-pci.mac=macaddr, The MAC address for the NIC.
virtio-net-pci.vlan=vlan, The VLAN to associate the NIC with.
virtio-net-pci.netdev=netdev, The peer net device to associate with this virtual NIC.
