drivers/net: set close behaviour flag at probing
The ethdev flag RTE_ETH_DEV_CLOSE_REMOVE is set for drivers having migrated to the new behaviour of rte_eth_dev_close(). As any other flag, it can be useful to know about its value as soon as the port is probed. Unfortunately, it was set inside the close operation, just before being erased by memset() in rte_eth_dev_release_port(). The flag assignment is moved to the probing stage, so it can be checked by the application in order to anticipate the behaviour. Fixes: 42603bbdb58e ("net/mlx5: release port on close") Fixes: 6c99085d972b ("net/vmxnet3: fix hot-unplug") Fixes: 4d7877fde2ef ("net/ena: remove resources when port is being closed") Signed-off-by: Thomas Monjalon <thomas@monjalon.net> Acked-by: Luca Boccassi <bluca@debian.org> Reviewed-by: Ferruh Yigit <ferruh.yigit@intel.com>
