Merge branch 'net-queue'

* net-queue: (28 commits)
  virtio-net: Increase filter and control limits
  virtio-net: Add new RX filter controls
  virtio-net: MAC filter optimization
  virtio-net: Fix MAC filter overflow handling
  virtio-net: reorganize receive_filter()
  virtio-net: Use a byte to store RX mode flags
  virtio-net: Add version_id 7 placeholder for vnet header support
  virtio-net: implement rx packet queueing
  net: make use of async packet sending API in tap client
  net: add qemu_send_packet_async()
  net: split out packet queueing and flushing into separate functions
  net: return status from qemu_deliver_packet()
  net: add return value to packet receive handler
  net: pass VLANClientState* as first arg to receive handlers
  net: re-name vc->fd_read() to vc->receive()
  net: add fd_readv() handler to qemu_new_vlan_client() args
  net: only read from tapfd when we can send
  net: vlan clients with no fd_can_read() can always receive
  net: move the tap buffer into TAPState
  net: factor tap_read_packet() out of tap_send()
  ...
