In order to support more than 256 virtual ports, the field "port" in
rte_mbuf has been increased to 16 bits. The initialization/reset
value of the field "port" should be changed from 0xff to 0xffff
accordingly.

Maybe introduce MBUF_INVALID_PORT as a constant?
#define MBUF_INVALID_PORT 0xffff

Replaced with below, or use UINT16_MAX directly?
