[Qemu-devel] [PATCH V4 RESEND 06/22] net: introduce qemu_find_net_clients_except() |
Date: |
Fri, 1 Feb 2013 15:39:40 +0800 |
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.
