[PATCH net-next] liquidio: Add support for liquidio 10GBase-T NIC

[Felix Manlunas]

From: Veerasenareddy Burru <veerasenareddy.bu...@cavium.com>

Added ethtool changes to show port type as TP (Twisted Pair) for
10GBASE-T ports. Same driver and firmware works for liquidio NIC with
SFP+ ports or TP ports.
