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.

net/mlx5: fix rule cleanup Netlink command sending
The VXLAN related rule cleanup routine queries and gathers all
existing local IP and neigh rules into buffer list. One buffer
may contain multiple rule deletion commands and is prepared
to send into Netlink as single message. But, if error occurs
for some deletion commands in the buffer, the multiple ACK
message with errors can be send back by the kernel. It breaks
the Netlink communication sequence numbers, because we expect
only one ACK message and it smashes out futher Netlik
communication.
The workaround of this problem is to send rule deletion commands
from buffer in one-by-one fashion and get ACK message for every
command sent. We do not expect too may rules preexist, so there
should not be critical performance degradation at VXLAN outer
interface initialization.

eal/x86: reduce contention when retrying TSX
When TSX transactions abort, it is generally worth retrying a number of
times before falling back to the traditional locking path, as the
parallelism benefits from TSX can be worth it when a transaction does
succeed. For cases with multiple threads and high contention rates, it
can be useful to have increasing delays between retry attempts, so as to
avoid having the same threads repeatedly collided.

ring/c11: keep deterministic order allowing retry to work
Use case scenario:
1) Thread 1 is enqueuing. It reads prod.head and gets stalled for some
reasons (running out of cpu time, preempted,...)
2) Thread 2 is enqueuing. It succeeds in enqueuing and moves prod.head
forward.
3) Thread 3 is dequeuing. It succeeds in dequeuing and moves the cons.tail
beyond the prod.head read by thread 1.
4) Thread 1 is re-scheduled. It reads cons.tail.
cpu1(producer) cpu2(producer) cpu3(consumer)
load r->prod.head
^ load r->prod.head
| load r->cons.tail
| store r->prod.head(+n)
stalled <-- enqueue ----->
| store r->prod.tail(+n)
| load r->cons.head
| load r->prod.tail
| store r->cons.head(+n)
| <...dequeue.....>
v store r->cons.tail(+n)
load r->cons.tail
For thread 1, the __atomic_compare_exchange_n detects the outdated
prod.head and retry the flow with the new one. This retry flow works ok on
strong ordering platform(eg:x86). But for weak ordering platforms(arm,
ppc), loading cons.tail and prod.head might be re-ordered, prod.head is new
but cons.tail becomes too old, the retry flow, based on the detection of
outdated head, does not trigger as expected, thus the outdate cons.tail
causes wrong free_entries.
Similarly, for dequeuing, outdated prod.tail leads to wrong avail_entries.
The fix is to keep the deterministic order of two loads allowing the retry
to work.

After removing the function rte_eth_dev_attach(),
there are two replacement solutions possible:
one using probe event notification, and one using a new iterator.
So the application can get the new probed ports either asynchronously
or synchronously.
The iterator API is new in DPDK 18.11 so they got the experimental
tag by policy. It causes an issue for strict applications which do
not use experimental functions, and want to use the synchronous method.
The replacement for removed API should not be experimental.
That's why the experimental status of the ethdev iterator is removed.

eal: remove experimental tag for probe/remove
The functions rte_dev_probe() and rte_dev_remove() are new
in DPDK 18.11 so they got the experimental tag by policy.
However they are too much basic functions for being skipped
by strict applications which do not use experimental functions.
The alternative is to use rte_eal_hotplug_add() and
rte_eal_hotplug_remove(), but their API requires the application
to parse the devargs string in order to provide bus name,
device name and driver arguments.
The new function rte_dev_probe() is really simpler to use and
more flexible by accepting any devargs string.
Let's encourage applications to use it.
The old functions rte_eal_hotplug_* may be deprecated later.

When creating an RSS rule without specifying a key (see [1]) it is

A NULL key is used to indicate to a PMD it should use

This does not enable testing any PMD behavior when the RSS key is not

- flow_verbs_translate_item_*() doesn't set parsing result -
MLX5_FLOW_LAYER_*.
- flow_verbs_translate_item_*() doesn't set priority or adjust hashfields
but does only item translation. Both have to be done outside.
- Make more consistent between Verbs and DV.

net/mlx5: add E-switch VXLAN tunnel devices management
VXLAN interfaces are dynamically created for each local UDP port
of outer networks and then used as targets for TC "flower" filters
in order to perform encapsulation. These VXLAN interfaces are
system-wide, the only one device with given UDP port can exist
in the system (the attempt of creating another device with the
same UDP local port returns EEXIST), so PMD should support the
shared device instances database for PMD instances. These VXLAN
implicitly created devices are called VTEPs (Virtual Tunnel
End Points).
Creation of the VTEP occurs at the moment of rule applying. The
link is set up, root ingress qdisc is also initialized.
Encapsulation VTEPs are created on per port basis, the single
VTEP is attached to the outer interface and is shared for all
encapsulation rules on this interface. The source UDP port is
automatically selected in range 30000-60000.
For decapsulaton one VTEP is created per every unique UDP
local port to accept tunnel traffic. The name of created
VTEP consists of prefix "vmlx_" and the number of UDP port in
decimal digits without leading zeros (vmlx_4789). The VTEP
can be preliminary created in the system before the launching
application, it allows to share UDP ports between primary
