The temporary flag RTE_ETH_DEV_CLOSE_REMOVE is removed.
It was introduced in DPDK 18.11 in order to give time for PMDs to migrate.

The old behaviour was to free only queues when closing a port.
The new behaviour is calling rte_eth_dev_release_port() which does
three more tasks:
	- trigger event callback
	- reset state and few pointers
	- free all generic port resources

The private port resources must be released in the .dev_close callback.

The .remove callback should:
	- call .dev_close callback
	- call rte_eth_dev_release_port()
	- free multi-port device shared resources

Despite waiting two years, some drivers have not migrated,
so they may hit issues with the incompatible new behaviour.
After sending emails, adding logs, and announcing the deprecation,
the only last solution is to declare these drivers as unmaintained:
	bnx2x, cxgbe, dpaa, dpaa2, enetc, ionic,
	ipn3ke,	liquidio, nfp, pfe, qede
Below is a summary of what to implement in those drivers.

* The freeing of private port resources must be moved
from the ".remove(device)" function to the ".dev_close(port)" function.

* If a generic resource (.mac_addrs or .hash_mac_addrs) cannot be freed,
it must be set to NULL in ".dev_close" function to protect from
subsequent rte_eth_dev_release_port() freeing.

* Note 1:
The generic resources are freed in rte_eth_dev_release_port(),
after ".dev_close" is called in rte_eth_dev_close(), but not when
calling ".dev_close" directly from the ".remove" PMD function.
That's why rte_eth_dev_release_port() must still be called explicitly
from ".remove(device)" after calling the ".dev_close" PMD function.

* Note 2:
If a device can have multiple ports, the common resources must be freed
only in the ".remove(device)" function.

* Note 3:
The port is supposed to be in a stopped state when it is closed.
If it is not the case, it is free to the PMD implementation
how to react when trying to close a non-stopped port:
either try to stop it automatically or just return an error.

For this note, 'rte_eth_dev_close()' assumes port stopped and sets 
"dev->data->dev_started = 0;" blindly.

should we verify this, or perhaps should call 'rte_eth_dev_stop()' 
within the 'rte_eth_dev_close()' to be sure.


Also many PMDs doesn't check primary process check in the close, which 
should be fixed too, I wonder if it can be fixed in this series?

I guess 'cxgbe' already send the patch, but for rest, is there a 
deadline for the patches, before mark them as "UNMAINTAINED"?

Good point. I wonder why dev_started is changed in the close.
It is set in rte_eth_dev_stop(), that should be enough.
But clearly it is a different issue which should be adressed separately.

You mean forbid close operation from secondary process?

OK

No need to forbid I think, and the not shared resource cleanup for 
secondary can be done in close function, but PMDs should have checks for 
the close calls from secondary processes to not free everything.

The pending PMD changes just dropped off the radar for quite some time. The patches for bnx2x and qede PMDs are submitted for 20.11 release, please apply.

Thanks!

-* ethdev: The temporary flag RTE_ETH_DEV_CLOSE_REMOVE will be removed in 20.11.
-  As a consequence, the new behaviour introduced in 18.11 will be effective
-  for all drivers: generic port resources are freed on close operation.
-  Private resources are expected to be released in the ``dev_close`` callback.
-  More details in http://inbox.dpdk.org/dev/5248162.j6AOsuQRmx@thomas/
-
 * ethdev: New offload flags ``DEV_RX_OFFLOAD_FLOW_MARK`` will be added in 19.11.
   This will allow application to enable or disable PMDs from updating
   ``rte_mbuf::hash::fdir``.
