Subject: [PATCH 17/59] amd-xgbe: Fixes for working with PHYs that support
2.5GbE
References: git-fixes
Patch-mainline: v4.13-rc1
Git-commit: ed3333fa6fc21b4191601367a5ea4f0f198f100d
The driver has some missing functionality when operating in the mode that
supports 2.5GbE. Fix the driver to fully recognize and support this speed.
