Merge branch 'amd-xgbe-next' 

Tom Lendacky says:

====================
amd-xgbe: AMD XGBE driver updates 2018-05-21

The following updates are included in this driver update series:

- Fix the debug output for the max channels count
- Read (once) and save the port property registers during probe
- Remove the use of the comm_owned field
- Remove unused SFP diagnostic support indicator field
- Add ethtool --module-info support
- Add ethtool --show-ring/--set-ring support
- Update the driver in preparation for ethtool --set-channels support
- Add ethtool --show-channels/--set-channels support
- Update the driver to always perform link training in KR mode
- Advertise FEC support when using a KR re-driver
- Update the BelFuse quirk to now support SGMII
- Improve 100Mbps auto-negotiation for BelFuse parts

This patch series is based on net-next.

---

Changes since v1:
- Update the --set-channels support to the use of the combined, rx and
  tx options as specified in the ethtool man page (in other words, don't
  create combined channels based on the min of the tx and rx channels
  specified).
