Using uint32_t type bit-fields in Windows will pads the
'L2/L3/L4 and tunnel information' union with additional bits.
This padding causes rte_mbuf size misalignment and the total size
increases to 3 cache-lines.
Changed packet_type bit-fields types from uint32_t to uint8_t
to allow unified 2 cache-line structure size.
Added the __extension__ attribute over the modified struct to avoid
the warning:
type of bit-field ... is a GCC extension [-pedantic]
