43e5488c0a net/i40e: support MTU configuration
This patch enables configuring MTU for i40e.
Since changing MTU needs to reconfigure queue, the port must be
stopped before configuring MTU.

bde516d5a8 ethdev: get port by name
Converted rte_eth_dev_get_port_by_name to a public API.
Converted rte_eth_dev_get_name_by_port to a public API.

The librte_pdump library provides the APIs to enable or disable the
packet capture either using the port id or pci address or device name.
So pdump library need to do a mapping from name to port and port to name
internally to validate the device name and register the Rx and Tx
callbacks for the mapped ports. So these APIs are made public for the
pdump library for doing the mentioned mappings.

00851d47f7 ethdev: get queues numbers
The new fields nb_rx_queues and nb_tx_queues are added to the
rte_eth_dev_info structure.
Changes to API rte_eth_dev_info_get() are done to update these new fields
to the rte_eth_dev_info object.
Release notes is updated with the changes.

The librte_pdump library needs to register Rx and Tx callbacks for all
the nb_rx_queues and nb_tx_queues, when application wants to capture the
packets on all the software configured number of Rx and Tx queues of the
device. So far there is no support to get nb_rx_queues and nb_tx_queues
information from the ethdev library. Hence these changes are introduced.

c8231c63dd ethdev: insert Rx callback as head of list
Added new public api rte_eth_add_first_rx_callback to add given
callback as head of the list.

The librte_pdump library should display Rx packets of the
NIC even before they are being processed by other callbacks
of the application (because other callbacks of the application
may change the packet data as part of the processing).
So packet capturing framework should register a callback at the
head of the Rx callback list so that callback always gets called
first before any other callbacks of the applications. Hence this API
is introduced.

4c50e2f6bf ethdev: refine API to query supported packet types
This change is to  make user code simpler. For PMDs which do not fill any
packet types, return 0 instead of -ENOTSUP as suggested by Bruce.

Usually, users only care if the required (by ptype_mask) ptypes can be
filled by the specified PMD. If the PMD implements dev_supported_ptypes_get
func is not important. And the introduce of another return value (-ENOTSUP)
would increase the complexity of user programs to check it.

Besides, there are ways to know if a PMD implements the func:
  a. see doc/guides/nics/overview.rst.
  b. use (~1) as parameter ptype_mask, then check if return 0.

2329a101f4 ethdev: fix xstats retrieval with a null array

If a user calls rte_eth_xstats_get(portid, NULL, n) with n != 0,
it may result in a crash. Although the API documentation says that
n is the size of the table and xstats can be NULL if n == 0, we
can add an additional check here to make Coverity happy.

In that case, the return value is the same than when n == 0 is
passed, it returns the number of statistics.

5db6b738c5 ethdev: fix possibly incorrect maximum queues
In rte_eth_dev_configure(), device configuration was copied to the dev
struct after get_dev_info() was called to get the max queue information.
In some drivers, though, the max queues can vary depending on the device
configuration - but that information is not available to the driver until
the copy is made.

This patch moves the memcpy of the device configuration into the dev->data
structure before the call to get_dev_info(), thereby making it accessible
to drivers to use when reporting their max queues.

So far, only vhost PMD supports the event, and it indicates some queues

first time the function is called with portid, xstats = NULL
and n = 0; this returns the number of entries in the statistics

and assumes that this is a valid pointer (it isn't). Device drivers
all have a check for NULL, and this no longer matches.

d6c99e62c8 ethdev: add buffered Tx
Many sample apps include internal buffering for single-packet-at-a-time
operation. Since this is such a common paradigm, this functionality is
better suited to being implemented in the ethdev API.

The new APIs in the ethdev library are:
* rte_eth_tx_buffer_init - initialize buffer
* rte_eth_tx_buffer - buffer up a single packet for future transmission
* rte_eth_tx_buffer_flush - flush any unsent buffered packets
* rte_eth_tx_buffer_set_err_callback - set up a callback to be called in
  case transmitting a buffered burst fails. By default, we just free the
  unsent packets.

As well as these, an additional reference callbacks are provided, which
frees the packets:

* rte_eth_tx_buffer_drop_callback - silently drop packets (default
  behavior)
* rte_eth_tx_buffer_count_callback - drop and update user-provided counter
  to track the number of dropped packets

but both should not be zero.
After above change, rte_eth_dev_tx_queue_config,
rte_eth_dev_rx_queue_config should allocate memory for rx/tx queues only
when number of rx/tx queues are nonzero.

525e478f5e ethdev: allow full control from secondary process
Macros RTE_PROC_PRIMARY_OR_ERR_RET and RTE_PROC_PRIMARY_OR_RET
are blocking the secondary process from using the APIs.
API access should be given to both secondary and primary.

5fa83b5398 ethdev: reduce alignment requirement for 128-byte cache line
slow-path data structures need not be 128-byte cache aligned.
Reduce the alignment to 64-byte to save the memory.

No behavior change for 64-byte cache aligned systems as minimum
cache line size as 64.
