Adding support to rte_eth_dev_data structure to support unique name identifier for ethdevs to support adding slave ethdevs (specifically virtual devices which have no public unique identifier) to a link bonding device. This changes the API rte_eth_dev_allocate() to require a const char *name when allocating a ethdev, which also verifies that the name is unique and hasn’t been already used by an existed allocated rte_eth_dev. Also contains updates to virtual pmd’s to now call the API with a name parameter. Signed-off-by: Declan Doherty <declan.doherty@intel.com> Acked-by: Pablo de Lara <pablo.de.lara.guarch@intel.com>
