6 years agoethdev: complete closing of port

ethdev: complete closing of port

After closing a port, it cannot be restarted.
So there is no reason to not free all associated resources.

The last step was done with rte_eth_dev_detach() which is deprecated.
Instead of blindly removing the associated rte_device, the driver should
check if no more port (ethdev, cryptodev, etc) is open for the device.

The last ethdev freeing which were done by rte_eth_dev_detach(),
are now done at the end of rte_eth_dev_close() if the driver supports
the flag RTE_ETH_DEV_CLOSE_REMOVE.
There will be a transition period for PMDs to enable this new flag
and migrate to the new behaviour.
When enabling RTE_ETH_DEV_CLOSE_REMOVE, the PMD must free all its
private resources for the port, in its dev_close function.
It is advised to call the dev_close function in the remove function
in order to support removing a device without closing its ports.

Some drivers does not allocate MAC addresses dynamically or separately.
In those cases, the pointer is set to NULL, in order to avoid wrongly
freeing them in rte_eth_dev_release_port().

A closed port will have the state RTE_ETH_DEV_UNUSED which is
considered as invalid by rte_eth_dev_is_valid_port().
So validity is not checked anymore for closed ports in testpmd.

net/enic: add missing Tx offload flags

The following commit has added a number of existing offload flags such
as PKT_TX_IPV4 and PKT_TX_IPV6 to PKT_TX_OFFLOAD_MASK defined in
rte_mbuf.h. That change breaks the enic driver's Tx prepare handler.

commit ef28cfa73822 ("mbuf: fix Tx offload mask")

The enic driver keeps the supported offload flags in a local variable
(tx_offload_mask), which is strictly a subset of
PKT_TX_OFFLOAD_MASK. This variable is then used to compute the
unsupported flags (tx_offload_notsup_mask), and the Tx prepare handler
(tx_pkt_prepare) uses it to reject packets with unsupported offload
flags.

As is, tx_offload_notsup_mask ends up containing flags like
PKT_TX_IPV4 that are actually supported by the driver, which then
breaks any application that uses checksum offloads and calls the Tx
prepare handler. So add the flags to tx_offload_mask that the driver
supports but were missing in PKT_TX_OFFLOAD_MASK.
