From 57407ea44cc0a3d630b9b89a2be011f1955ce5c1 Mon Sep 17 00:00:00 2001 From: Paolo Bonzini Date: Tue, 23 Dec 2014 17:53:19 +0100 Subject: net: remove all cleanup methods from NIC NetClientInfos All NICs have a cleanup function that, in most cases, zeroes the pointer to the NICState. In some cases, it frees data belonging to the NIC. However, this function is never called except when exiting from QEMU. It is not necessary to NULL pointers and free data here; the right place to do that would be in the device's unrealize function, after calling qemu_del_nic. Zeroing the NIC multiple times is also wrong for multiqueue devices. This cleanup function gets in the way of making the NetClientStates for the NIC hold an object_ref reference to the object, so get rid of it.
