8dc775d8b1 net/mlx5: fix event queue number query
When a Rx\Tx queue is created by DevX, its CQ configuration should
include the EQ number of the interrupts.
The EQ is managed by the kernel and there is a glue API in order to
query the EQ number from the kernel.
The EQ query API gets a vector number specifies the kernel vector of
the interrupt handling.

The vector number was wrongly detected according to the configuration
CPU instead of using the device attributes of the supported vectors.
The CPU was wrongly detected by the rte_lcore_to_cpu_id API without any
check, and in case of non-EAL thread context the value was 0xFFFFFFFF
which caused a failure in the EQ number query API.

Use vector 0 for each EQ number query which must be supported by the
kernel.

9ab9d46ab9 net/mlx5: fix Tx queue release
The HW objects of the Tx queue is created/destroyed in the device
start\stop stage while the ethdev configurations for the Tx queue
starts from the tx_queue_setup stage.
The PMD should save all the last configurations it got from the ethdev
and to apply them to the device in the dev_start operation.

Wrongly, last code added to mitigate the reference counters didn't take
into account the above rule and combined the configurations and HW
objects to be created\destroyed together.

This causes to memory leak and other memory issues.

Make sure the HW object is released in stop operation when there is no
any reference to it while the configurations stay saved.

c0d002aed9 gso: fix mbuf freeing responsibility
rte_gso_segment decreased refcnt of pkt by one, but
it is wrong if pkt is external mbuf, pkt won't be
freed because of incorrect refcnt, the result is
application can't allocate mbuf from mempool because
mbufs in mempool are run out of.

One correct way is application should call
rte_pktmbuf_free after calling rte_gso_segment to free
pkt explicitly. rte_gso_segment must not handle it, this
should be responsibility of application.

This commit changed rte_gso_segment in functional behavior
and return value, so the application must take appropriate
actions according to return values, "ret < 0" means it
should free and drop 'pkt', "ret == 0" means 'pkt' isn't
GSOed but 'pkt' can be transmitted as a normal packet,
"ret > 0" means 'pkt' has been GSOed into two or multiple
segments, it should use "pkts_out" to transmit these
segments. The application must free 'pkt' after call
rte_gso_segment when return value isn't equal to 0.

af270529ad ethdev: include mbuf registration in Tx timestamp API
Previously, the Tx timestamp field and flag were registered in testpmd,
as described in mlx5 guide.
For consistency between Rx and Tx timestamps,
managing mbuf registrations inside the driver, as properly documented,
is a simpler expectation.

The only driver to support this feature (mlx5) is updated
as well as the testpmd application.

c667583d82 event/dlb2: add token pop API
The PMD uses a public interface to allow applications to
control the token pop mode. Supported token pop modes are
as follows, and they impact core scheduling affinity for
ldb ports.

AUTO_POP: Pop the CQ tokens immediately after dequeueing.
DELAYED_POP: Pop CQ tokens after (dequeue_depth - 1) events
             are released. Supported on load-balanced ports
             only.
DEFERRED_POP: Pop the CQ tokens during next dequeue operation.

a2e4f1f5e7 event/dlb2: add dequeue and its burst variants
Add support for dequeue, dequeue_burst, ...

DLB2 does not currently support interrupts, but instead use
umonitor/umwait if supported by the processor. This allows
the software to monitor and wait on writes to a cache-line.

DLB2 supports normal and sparse cq mode. In normal mode the
hardware will pack 4 QEs into each cache line. In sparse cq
mode, the hardware will only populate one QE per cache line.
Software must be aware of the cq mode, and take the appropriate
actions, based on the mode.
