[PATCH] pcap: set in_port value in packet mbuf data when each packet is received

[PATCH] pcap: set in_port value in packet mbuf data when each packet is received

[Saori USAMI]

The pkt.in_port parameter in mbuf should be set with an input port id
because DPDK apps may use it to know where each packet came from.

Hi,

How about the following patch for the next DPDK release?

Thanks,

Acked, adapted to mbuf rework and applied.

Thanks
