Merge branch 'enetc-mac-merge-prep'
Vladimir Oltean says:
====================
ENETC MAC Merge cleanup
This is a preparatory patch set for MAC Merge layer support in enetc via
ethtool. It does the following:
- consolidates a software lockstep register write procedure for the pMAC
- detects per-port frame preemption capability and only writes pMAC
registers if a pMAC exists
- stops enabling the pMAC by default
Additionally, I noticed some build warnings in the driver which are new
in this kernel version, so patch 1/6 fixes those.
