Port detaching processes are different between PCI device and virtual device. RTE_ETH_DEV_PCI indicates device type is PCI. RTE_ETH_DEV_VIRTUAL indicates device is virtual. v12: - Add missing symbol in version map. (Thanks to Iremonger, Bernard) v10: - Change order of version.map. (Thanks to Thomas Monjalon) - Fix comment of "rte_ethdev.h". (Thanks to Thomas Monjalon) v9: - Fix commit log. - RTE_ETH_DEV_PHYSICAL is replaced by RTE_ETH_DEV_PCI. (Thanks to Thomas Monjalon) v8: - NONE_TRACE is replaced by NO_TRACE. - Add missing symbol in version map. (Thanks to Qiu, Michael and Iremonger, Bernard) v4: - Fix comments of rte_eth_dev_type.
