[Qemu-devel] [PATCH v2 4/6] net: force NetQue opaque to be NetClientState

[Liu Ping Fan <qemulist@gmail.com>]

From: Liu Ping Fan <pingfanl@linux.vnet.ibm.com>

qemu_net_client_setup() is the only user of qemu_new_net_queue(), which
will pass in NetClientState. By forcing it be a NetClientState, we
can ref/unref NetQueue's owner
