e3b91a3ef2 test/crypto: fix possible overflow using strlcat
strcat does not check the destination length and there might be
chances of string overflow so instead of strcat, strlcat is used.

2382aa8c8f cryptodev: fix driver name comparison
The string compare to the length of driver name might give false
positives when there are drivers with similar names (one being the
subset of another).

Following is such a naming which could result in false positive.
1. crypto_driver
2. crypto_driver1

When strncmp with len = strlen("crypto_driver") is done, it could give
a false positive when compared against "crypto_driver1". For such cases,
'strlen + 1' is done, so that the NULL termination also would be
considered for the comparison.

27e71c7fdc cryptodev: restore crypto op alignment and layout
in 18.08 new cache-aligned structure rte_crypto_asym_op was introduced.
As it also was included into rte_crypto_op, it caused implicit change
in rte_crypto_op layout and alignment: now rte_crypto_op is cache-line
aligned has a hole of 40/104 bytes between phys_addr and sym/asym op.
It looks like unintended ABI breakage, plus such change can cause
negative performance effects:
- now status and sym[0].m_src lies on different cache-lines, so
  post-process code would need extra cache-line read.
- new alignment causes grow of the space requirements and cache-line
  reads/updates for structures that contain rte_crypto_op inside.
As there seems no actual need to have rte_crypto_asym_op cache-line
aligned, and rte_crypto_asym_op is not intended to be used on it's own -
the simplest fix is just to remove cache-line alignment for it.
As the immediate positive effect: on IA ipsec-secgw performance increased
by 5-10% (depending on the crypto-dev and algo used).
My guess that on machines with 128B cache-line and lookaside-protocol
capable crypto devices the impact will be even more noticeable.

3e0396166b vhost: support requests only handled by external backend
External backends may have specific requests to handle, and so
we don't want the vhost-user lib to handle these requests as
errors.

This patch also changes the experimental API by introducing
RTE_VHOST_MSG_RESULT_NOT_HANDLED so that vhost-user lib
can report an error if a message is handled neither by
the vhost-user library nor by the external backend.

The logic changes a bit so that if the callback returns
with ERR, OK or REPLY, it is considered the message
is handled by the external backend so it won't be
handled by the vhost-user library.
It is still possible for an external backend to listen
to requests that have to be handled by the vhost-user
library like SET_MEM_TABLE, but the callback have to
return NOT_HANDLED in that case.

Vhost-crypto backend is also adapted to this API change.

c68fee9588 net/virtio: fix interrupt helper for packed ring
When disabling interrupt, the shadow event flags should also be
updated accordingly. The unnecessary wmb is also dropped.

2f706027c8 vhost: fix interrupt suppression for the split ring
The VIRTIO_RING_F_EVENT_IDX feature of split ring might
be broken, as the value of signalled_used is invalid
after live migration, start up and virtio driver reload.
This patch fixes it by using signalled_used_valid.

In addition, this patch makes the VIRTIO_RING_F_EVENT_IDX
implementation of split ring match kernel backend to suppress
more interrupts.

bad78b4b8b net/virtio-user: fix multiqueue with vhost kernel
The multiqueue support in virtio-user with vhost kernel backend
is broken when tap name isn't specified by users explicitly,
because the tap name returned by ioctl(TUNSETIFF) isn't saved
properly, and multiple tap interfaces will be created in this
case. Fix this by saving the dynamically allocated tap name
first before reusing the ifr structure. Besides, also make it
possible to support the format string in tap name (e.g. foo%d)
specified by users explicitly.

11d5253a3e vhost: prevent disabled rings to be processed with zero-copy
The vhost-user spec says that once the vring is disabled, the
client has to stop processing it. But it can happen when
dequeue zero-copy is enabled if outstanding descriptors buffers
are still being processed by an external NIC or another guest.

The fix consists in draining the zmbufs list to ensure no more
descriptors buffers are in the wild.

Note that this fix is only working in the case REPLY_ACK
protocol feature is enabled, which is not the case by default
for now (it is only enabled when IOMMU feature is enabled in
the vhost library).

b4ec00a254 net/octeontx: fix vdev name
The octeontx driver is creating vdev with name  "OCTEONTX_PMD"
which is an artifact from how RTE_PMD_REGISTER_VDEV arguments
work.

Change to use the same convention as all the other network
drivers ie "net_octeontx").
