Hi to everyone!

A couple of questions about DPDK:

1. Can Intel DPDK work with double tagged ethernet frames? To read frame with 2 tags and to write frame to the wire with two tags (QinQ technology)

2. Can Intel DPDK read and write MPLS tags?

It reads/writes raw packets, what protocol you want to use is up to you.
