[Qemu-devel] [PATCH V2 04/20] net: introduce qemu_find_net_clients_except() |

In multiqueue, all NetClientState that belongs to the same netdev or nic has the
same id. So this patches introduces an helper qemu_find_net_clients_except()
which finds all NetClientState with the same id. This will be used by multiqueue
networking.
