Subject: liquidio: Add support for liquidio 10GBase-T NIC
Patch-mainline: v4.17-rc1
Git-commit: 5677629a5a091a62512427534404b509fe6c615d
References: bsc#1119406 FATE#326562

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.
