I'm not sure it overlaps.
RTE_ETH_LINK_CONNECTOR is about Ethernet cables while
pcap link type will be simply Ethernet type.

This being said, I don't understand the immediate benefit of this commit.
Why pcap link type would not be always Ethernet in DPDK case?
I think the only benefit is for future if other link types are added.
Is there something else I'm missing?
