[dpdk-dev] [PATCH v4 06/14] net/pfe: add MAC and host interface initialisation

[Gagandeep Singh <g.singh@nxp.com>]

HIF or host interface is responsible for transmit
and receive packets between physical ethernet
interfaces and HIF library defined logical interfaces.

This patch initialise that host interface and MAC.
