It's not possible to setup a queue when the port is started
because of a check in ethdev layer. New capability flags are
added in order to relax this check for devices which support
queue setup in runtime. The functions rte_eth_[rx|tx]_queue_setup
will raise an error only if the port is started and runtime setup
of queue is not supported.

The feature was added at the end of the table.
And the description was between the anchor _nic_features_timesync
and its title.
It is moved near related features with a new anchor.
It is also renamed from "mbuf fast free" to "fast mbuf free".

PMDs which expose this offload cap supports optimization for fast release
of mbufs following successful Tx.
Such optimization requires that per queue, all mbufs come from the same
mempool and has refcnt = 1.

Introducing the DEV_TX_OFFLOAD_MT_LOCKFREE TX capability flag.
if a PMD advertises DEV_TX_OFFLOAD_MT_LOCKFREE capable, multiple threads
can invoke rte_eth_tx_burst() concurrently on the same tx queue without
SW lock. This PMD feature will be useful in the following use cases and
found in the OCTEON family of NPUs.
1) Remove explicit spinlock in some applications where lcores
to TX queues are not mapped 1:1.
example: OVS has such instance
https://github.com/openvswitch/ovs/blob/master/lib/netdev-dpdk.c#L299https://github.com/openvswitch/ovs/blob/master/lib/netdev-dpdk.c#L1859
See the the usage of tx_lock spinlock.
2) In the eventdev use case, avoid dedicating a separate TX core for
transmitting and thus enables more scaling as all workers can
send the packets.

This new API allows reacting to a device removal.
A device removal is the sudden disappearance of a device from its
bus.
PMDs implementing support for this notification guarantee that the removal
of the underlying device does not incur a risk to the application.
In particular, Rx/Tx bursts and all other functions can still be called
(albeit likely returning errors) without triggering a crash, irrespective
of an application handling this event.

Introduce a new API to get the status of a descriptor.
For Rx, it is almost similar to rx_descriptor_done API, except it
differentiates "used" descriptors (which are hold by the driver and not
returned to the hardware).
For Tx, it is a new API.
The descriptor_done() API, and probably the rx_queue_count() API could
be replaced by this new API as soon as it is implemented on all PMDs.

Convert the NIC feature table in the overview doc into a set of ini
files and add functions into the Sphinx conf.py file to auto-generate
them back into an RST table.
The reason for doing this is to make it easier for PMD maintainers to
update the feature matrix that makes up the table and to avoid
frequent and hard to resolve conflicts in doc/guides/nics/overview.rst.
A NIC/PMD feature matrix is now an ini file like the following:
$ head doc/guides/nics/nic_features/i40e.ini
;
; Features of the i40e network driver.
;
[Features]
Link status = Y
Link status event = Y
Rx interrupt = Y
Queue start/stop = Y
...
The output RST table matches the existing table with the column
headers sorted.
