Introduces a new port attribute to ethdev port's which denotes the
switch domain a port belongs to. By default all port's switch
identifiers are set to RTE_ETH_DEV_SWITCH_DOMAIN_ID_INVALID. Ports
which supported the concept of switch domains can be configured with
the same switch domain id.

One miss: you forgot to remove the deprecation notice in this patch.

    Target release for removal of the legacy API will be defined once most

  -* ethdev: A work is being planned for 18.05 to expose VF port representors
  -  as a mean to perform control and data path operation on the different VFs.
  -  As VF representor is an ethdev port, new fields are needed in order to map
  -  between the VF representor and the VF or the parent PF. Those new fields
  -  are to be included in ``rte_eth_dev_info`` struct.
  -
   * i40e: The default flexible payload configuration which extracts the first 16
     bytes of the payload for RSS will be deprecated starting from 18.02. If
     required the previous behavior can be configured using existing flow
