[dpdk-dev] [PATCH 4/7] net/ixgbe/base: support Marvell 1000BASE-T PHYs

[Wei Dai]

This patch adds initial support for Marvell 1000BASE-T PHYs
on Broadwell-DE.
Firmware owns the link config for Marvell PHYs on Broadwell-DE,
software should not touch it.
Also Broadwell-DE is not capable of speeds lower than 1Gb.
