====================
amd-xgbe: AMD XGBE driver updates 2015-03-19

The following series of patches includes functional updates and changes
to the driver.

- Use the phydev->advertising field instead of the phydev->supported
  field when configuring for auto-negotiation, etc.
- Use the phy_driver flags field for setting the transceiver type
  instead of hardcoding it in the ethtool support.
- Provide an auto-negotiation timeout check
- Clarify the Tx/Rx queue information messages
- Use the new DMA memory barrier operations
- Set the device DMA mask based on what the hardware reports
- Remove the software implementation of Tx coalescing
- Fix the reporting of the Rx coalescing value
- Use napi_alloc_skb when allocating an SKB in softirq

This patch series is based on net-next.

Changes from v2:
- Use jiffies instead of timespec for the auto-negotiation timeout check
- Remove the Rx path SKB allocation re-work patch since we should only
  inline the headers and the current code guards better against any
  hardware bugs

Changes from v1:
- Default to 32-bit DMA width (minimum supported) if hardware returns
  an unexpected DMA width value
