From 6c51ae73fc68de2a4f11f5a7ebb52a4e79687e7d Mon Sep 17 00:00:00 2001 From: Jason Wang Date: Wed, 30 Jan 2013 19:12:25 +0800 Subject: 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.
