af_packet driver needs to check VLIB_BUFFER_NEXT_PRESENT flag is set
when walking  vlib_buffer_t next_buffer chain on transmit.
On buffer allocation:
- next_buffer is not and may contain a stale invalid value that
  should be ignored if not overwritten by a valid value.
- VLIB_BUFFER_NEXT_PRESENT flag is cleared and only set
  if a valid value is written to next_buffer.
