Merge branch 'amd-xgbe-next'

Tom Lendacky says:

====================
amd-xgbe: AMD XGBE driver updates 2017-08-17

The following updates are included in this driver update series:

- Set the MDIO mode to clause 45 for the 10GBase-T configuration
- Set the MII control width to 8-bits for speeds less than 1Gbps
- Fix an issue to related to module removal when the devices are up
- Fix ethtool statistics related to packet counting of TSO packets
- Add support for device renaming
- Add additional dynamic debug output for the PCS window calculation
- Optimize reading of DMA channel interrupt enablement register
- Add additional dynamic debug output about the hardware features
- Add per queue Tx and Rx ethtool statistics
- Add a macro to clear ethtool_link_ksettings modes
- Convert the driver to use the ethtool_link_ksettings
- Add support for VXLAN offload capabilities
- Add additional ethtool statistics related to VXLAN

This patch series is based on net-next.
