Jeff Kirsher says:

====================
This series contains updates to ixgbe only.  Only change to this series
is I dropped the "ixgbe: Add support for pipeline reset" due to
change requested by Martin Josefsson.

Alexander Duyck (7):
  ixgbe: Add support for IPv6 and UDP to ixgbe_get_headlen
  ixgbe: Add support for tracking the default user priority to SR-IOV
  ixgbe: Add support for GET_QUEUES message to get DCB configuration
  ixgbe: Enable support for VF API version 1.1 in the PF.
  ixgbevf: Add VF DCB + SR-IOV support
  ixgbe: Drop unnecessary addition from ixgbe_set_rx_buffer_len
  ixgbe: Fix possible memory leak in ixgbe_set_ringparam

Don Skidmore (1):
  ixgbe: Add function ixgbe_reset_pipeline_82599

Emil Tantilov (1):
  ixgbe: add WOL support for new subdevice id

Jacob Keller (1):
  ixgbe: (PTP) refactor init, cyclecounter and reset

Tushar Dave (1):
  ixgbe: Correcting small packet padding

Wei Yongjun (1):
  ixgbe: using is_zero_ether_addr() to simplify the code
