  For supporting XDP_REDIRECT, a device driver must (obviously)
  implement the "TX" function ndo_xdp_xmit(). An additional requirement
  is you cannot TX out a device, unless it also have a xdp bpf program
  attached. This dependency is caused by the driver code need to setup
  XDP resources before it can ndo_xdp_xmit.

  Update bpf samples xdp_redirect and xdp_redirect_map to automatically
  attach a dummy XDP program to the configured ifindex_out device. Use
  the XDP flag XDP_FLAGS_UPDATE_IF_NOEXIST on the dummy load, to avoid
  overriding an existing XDP prog on the device.

• 832622e6b   xdp: sample program for new bpf_redirect helper ... Browse Code »

  This implements a sample program for testing bpf_redirect. It reports
  the number of packets redirected per second and as input takes the
  ifindex of the device to run the xdp program on and the ifindex of the
  interface to redirect packets to.
