Merge branch 'amd-xgbe-updates'

Tom Lendacky says:

====================
amd-xgbe: AMD XGBE driver updates 2016-11-03

This patch series is targeted at preparing the driver for a new PCI version
of the hardware.  After this series is applied, a follow-on series will
introduce the support for the PCI version of the hardware.

The following updates and fixes are included in this driver update series:

- Fix formatting of PCS debug register dump
- Prepare for priority-based FIFO allocation
- Implement priority-based FIFO allocation
- Prepare for working with more than one type of PCS/PHY
- Prepare for the introduction of clause 37 auto-negotiation
- Add support for clause 37 auto-negotiation
- Prepare for supporting a new PCS register access method
- Add support for 64-bit management counter registers
- Update DMA channel status determination
- Prepare for supporting PCI devices in addition to platform devices

This patch series is based on net-next.
