Merge branch 'xgbe-next'

Tom Lendacky says:

====================
amd-xgbe: AMD 10Gb Ethernet driver updates

The following series fixes some bugs and provides new/changed support
in the driver.

- Make all the defines in the xgbe.h file unique by prefixing them with
  XGBE_ if they are not currently using the prefix.
- VLAN CTAGs are supplied in context descriptors. Tell the hardware to
  look in the Tx context descriptor, and not a register, for the VLAN CTAG
  to be inserted in the packet.
- The hardware will indicate a VLAN packet has been received even if VLAN
  CTAG stripping is currently disabled.  Only indicate that a VLAN CTAG
  has been stripped for the current packet if stripping is enabled.
- Add support for VLAN filtering
- Modify destination address filtering to use the hardware hash tables
- Eliminate a checkpatch warning by replacing sscanf with kstrtouint

This patch series is based on net-next.
