This new parameter is needed to keep device type like PCI or virtual.
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.
v15:
- Remove needless symbols in version.map
- Move rte_eth_dev_get_device_type() to later patch to compile
correctly.
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.
