* remotes/stefanha/tags/net-pull-request:
  virtio-net: use qemu_get_queue() where possible

  net: remove implicit peer from offload API
  net: Disable netmap backend when not supported
  net: add offloading support to netmap backend
  net: make tap offloading callbacks static
  net: virtio-net and vmxnet3 use offloading API
  net: TAP uses NetClientInfo offloading callbacks
  net: extend NetClientInfo for offloading
  net: change vnet-hdr TAP prototypes
  opencores_eth: flush queue whenever can_receive can go from false to true
