5ee6cef267 cryptodev: remove experimental label
The cryptodev API was introduced in the DPDK 2.2 release.
Since then it has
 - been reviewed and iterated for the DPDK 16.04 release
 - had extensive use by the l2fwd-crypto app,
			the ipsec-secgw example app,
			the test app.
We believe it is now stable and the EXPERIMENTAL label should be removed.

5d7bfb7337 hash: fix race condition at creation
To avoid a race condition while creating a new hash object, the
list has to be locked before the lookup, and released only once the
new object is added in the list.

As the lock is held by the rte_ring_create(), move its creation at the
beginning of the function and only take the lock after the ring is
created to avoid a deadlock.

1aadacb5b0 hash: fix allocation of an existing object
Change rte_hash*_create() functions to return NULL and set rte_errno to
EEXIST when the object name already exists. This is the behavior
described in the API documentation in the header file.

These functions were returning a pointer to the existing object in that
case, but it is a problem as the caller did not know if the object had
to be freed or not.

Doing this change also makes the hash API more consistent with the other
APIs (mempool, rings, ...).

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
Coverity reports an issue in ethdev:

  *** CID 124562:  Null pointer dereferences  (FORWARD_NULL)
  /lib/librte_ether/rte_ethdev.c: 1518 in rte_eth_xstats_get()

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.

- it allows to define a set of advertised speeds for

- it allows to disable link auto-negociation (single fixed speed).

f9bd334211 hash: fix multi-process support
Hash library used a function pointer to choose a different
key compare function, depending on the key size.
As a result, multiple processes could not use the same hash table,
as the function addresses vary from one process to another.

Instead, a jump table is used, so each process has its own
function addresses, accessing this table with an index stored
in the hash table (note that using a custom key compare function
is not supported in multi-process mode).

a88ba49e51 config: fix CPU and memory parameters on IBM POWER8
This patch fixes the max logic number and memory channel number settings
on IBM POWER8 platform.
1. The max number of logic cores of a POWER8 processor is 96. Normally,
   there are two sockets on a server. So the max number of logic cores
   are 192. So this parch set CONFIG_RTE_MAX_LCORE to 256.
2. The socket number on POWER8 little endian platform can be larger than 16.
   This patch set CONFIG_RTE_MAX_NUMA_NODES to 32 for POWER8.
3. Currently, the max number of memory channels are hardcoded to 4. However,
   on a POWER8 machine, the max number of memory channels are 8. This patch
   removes the constraint.

5db6b738c5 ethdev: fix possibly incorrect maximum queues
In rte_eth_dev_configure(), device configuration was copied to the dev

the copy is made.

This patch moves the memcpy of the device configuration into the dev->data

    success = rte_atomic32_cmpset(&r->cons.head, cons_head, cons_next);

The same is possible on the enqueue path.

768f0e4587 lpm6: fix use after free
In certain autotests lpm->max_rules turned out to be non initialized.
That was caused by a failing allocation for lpm->rules_tbl in rte_lpm6_create.
It then left the function via goto exit with lpm freed, but still a pointer
value being set.

In case of an allocation failure it resets lpm to NULL now, to avoid the
upper layers operate on that already freed memory.
Along that is also makes the RTE_LOG message of the failed allocation unique.

732a5b5c53 lpm6: fix missing free
lpm6 autotests failed with the default alloc of 512M Memory.
While >=2500M was a workaround it became clear while debugging that it
had a leak.
One could see a lot of output like:
  LPM Test tests6[i]: FAIL
  LPM: LPM memory allocation failed

It turned out that in rte_lpm6_free
- lpm might not be freed if it didn't find a te (early return)
- lpm->rules_tbl was not freed ever

34c4b5846e lpm: fix use after free
There were further chances for a use after free by returning an already
freed pointer in rte_lpm_create for v20 and v1604.
Along that is also makes the RTE_LOG messages of the failed allocations
unique.

d4c18f0a1d lpm: fix missing free
In rte_lpm_free lpm might not be freed if it didn't find a te (early return)

The two lpm interfaces rte_lpm_free_v20 and rte_lpm_free_v1604 had a leak.
rte_lpm_free_v20 might have missed to free rules_tbl
rte_lpm_free_v1604 due to an early exit might have missed to free
rules_tbl and lpm itself.

b3869ebebf vhost: remove unnecessary memset when enqueueing
We have to reset the virtio net hdr at virtio_enqueue_offload()
before, due to all mbufs share a single virtio_hdr structure:

	struct virtio_net_hdr_mrg_rxbuf virtio_hdr = {{0, }, 0};

	foreach (mbuf) {
		virtio_enqueue_offload(mbuf, &virtio_hdr.hdr);

		copy net hdr and mbuf to desc buf
	}

However, after the vhost rxtx refactor, the code looks like:

	copy_mbuf_to_desc(mbuf)
	{
		struct virtio_net_hdr_mrg_rxbuf virtio_hdr = {{0, }, 0}

		virtio_enqueue_offload(mbuf, &virtio_hdr.hdr);

		copy net hdr and mbuf to desc buf
	}

	foreach (mbuf) {
		copy_mbuf_to_desc(mbuf);
	}

Therefore, the memset at virtio_enqueue_offload() is not necessary
any more; remove it.
