Jerr Kirsher says:

====================
This series contains updates to ixgbe & ixgbevf.
 ...
Alexander Duyck (6):
  ixgbe: Ping the VFs on link status change to trigger link change
  ixgbe: Handle failures in the ixgbe_setup_rx/tx_resources calls
  ixgbe: Move configuration of set_real_num_rx/tx_queues into open
  ixgbe: Update the logic for ixgbe_cache_ring_dcb and DCB RSS
    configuration
  ixgbe: Cleanup logic for MRQC and MTQC configuration
  ixgbevf: Update descriptor macros to accept pointers and drop _ADV
    suffix
====================
