The function rte_eth_dev_detach() is freeing a port and its underlying
rte_device object. The issue is that we may have several ports
associated to the same rte_device.
The right replacement is to free the port, and free the rte_device
if no more ports.
At ethdev level, the public function for port freeing is rte_eth_dev_close().
The only miss is rte_eth_dev_release_port() to free all port resources.
This patchset does a cleanup by moving as much ethdev data freeing
as possible in an unique function rte_eth_dev_release_port(),
and call this function in rte_eth_dev_close().
The port is released on close only if the driver supports it.
Changes in v6:
- fix testpmd ports list iteration
- keep old behaviour
- add flag RTE_ETH_DEV_CLOSE_REMOVE to enable new behaviour (port release)
Changes in v5:
- fix testpmd for detaching multi-ports device
- fix testpmd for detaching only stopped ports
- add a release note about closed port freeing and state
- fix some doxygen comments in rte_eth_dev_data
- improve doxygen of rte_eth_dev_release_port()
- fix data freeing in some drivers
Changes in v4:
- do not free data fields which are not dynamically allocated blocks
- remove rte_eth_dev_release_port_secondary()
- remove testpmd check to detach without closing
Changes in v3:
- free queues, MAC addresses and private structure
in rte_eth_dev_release_port.
Thomas Monjalon (5):
app/testpmd: allow detaching a port not closed
ethdev: fix doxygen comments of shared data fields
ethdev: free all common data when releasing port
ethdev: remove release function for secondary process
ethdev: complete closing of port
Wisam Jaddo (1):
app/testpmd: update port list for multiple removals
