[dpdk-dev] [PATCH] net/nfp: add port id to mbuf

[Alejandro Lucero]

Although this can be done by the app, because other PMDs are doing it,
apps expect this behaviour from the PMD.

Although it doesn't explicitly stated, I think expectation is PMD to set it, the
sample applications I checked in the dpdk don't set this.

And it can give better performance setting in PMD where the data is hot.
