Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next 

Jerr Kirsher says:

====================
This series contains updates to ixgbe.
 ...
Alexander Duyck (9):
  ixgbe: Use VMDq offset to indicate the default pool
  ixgbe: Fix memory leak when SR-IOV VFs are direct assigned
  ixgbe: Drop references to deprecated pci_ DMA api and instead use
    dma_ API
  ixgbe: Cleanup configuration of FCoE registers
  ixgbe: Merge all FCoE percpu values into a single structure
  ixgbe: Make FCoE allocation and configuration closer to how rings
    work
  ixgbe: Correctly set SAN MAC RAR pool to default pool of PF
  ixgbe: Only enable anti-spoof on VF pools
  ixgbe: Enable FCoE FSO and CRC offloads based on CAPABLE instead of
    ENABLED flag
====================
