af_packet driver failure to check VLIB_BUFFER_NEXT_PRESENT flag
af_packet driver must check that 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.
