This patch adds "RTE_PCI_DRV_DETACHABLE" to drv_flags of rte_pci_driver structure. The flags indicate the driver can detach devices at runtime. Also, remove assumption that port will not be detached. To remove the assumption. - Add 'attached' member to rte_eth_dev structure. This member is used for indicating the port is attached, or not. DEV_ATTACHED indicates a port is attached. DEV_DETACHED indicates a port is detached. - Add rte_eth_dev_allocate_new_port(). This function is used for allocating new port. v9: - DEV_INVALID/VALID are removed. - DEV_DISCONNECTED is replaced by DEV_DETACHED. - DEV_CONNECTED is replaced by DEV_ATTACHED. - rte_eth_dev_allocate_new_port() is renamed to rte_eth_dev_find_free_port(). - rte_eth_dev_validate_port() is renamed to rte_eth_dev_is_valid_port(). - rte_eth_dev_is_valid_port() is changed not to handle log toggle. - Fix commit log to describe DEV_ATACHED and DEV_DETACHED. (Thanks to Thomas Monjalon) v8: - NONE_TRACE is changed to NO_TRACE. (Thanks to Iremonger, Bernard) v5: - Change parameters of rte_eth_dev_validate_port() to cleanup code. v4: - Use braces with 'for' loop. - Fix indent of 'if' statement.
