[dpdk-dev] [PATCH v7 2/9] ethdev: add switch identifier parameter to port

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.
