21d0b0433c crypto/scheduler: fix ring dequeue return handling
Commit <ecaed092b677> ("ring: return remaining entry count when
dequeuing") changed the return of rte_ring_sc_dequeue_bulk.
This patch updates the scheduler to comply with this change.

c64457cb11 examples/l2fwd-crypto: fix padding calculation
For padding calculation, it is necessary to know if algorithm
is a block cipher or stream cipher algorithm, and know the
block size for the algorithm.

In the application, this block size should be only the
cipher block size, but if authentication was used too,
it was being overwritten by the authentication block size,
which is not needed.

168b9e76f9 drivers/crypto: do not create unique name internally
Crypto devices of the same type could be initialized
with the same name, since internally this name was suffixed
with an index.

Since commit <dda987315ca2> ("vdev: make virtual bus use its
device struct"), this is not allowed anymore.

Therefore, there is no need to create an unique name
at device initialization.

d2797f51cc examples/l2fwd-crypto: add cryptodev mask option
Previously, l2fwd-crypto application did not give user the
flexibility to decide which crypto device(s) will be used.

2e516d18dc event/sw: fix events mis-identified as needing reorder
When taking events from a port, we checked the history list to check if the
event needed to be put back in order i.e. originally came from a reordered
queue type. The check for reordering involved checking if the reorder
buffer entry pointer was null. However, after that pointer was used it was
never cleared to null again.

This caused problems when we had mixed reordered and atomic or parallel
events, as the events from the latter two queue types were misidentified as
needing reordering. This let in some cases to crashes, but mostly led to
dropping events, and then application lock-up.

84ad6e4491 vhost: fix dequeue zero copy
For zero copy mode, we need pin the mbuf to not let the underlaying PMD
driver (or the app) free the mbuf. Currently, only the heading mbuf is
pinned. However, the mbuf free function would try to free all mbufs
in the mbuf chain (-1 to the refcnt). This may lead the head mbuf being
still pinned, while the other subsequent mbufs are actually freed. Which
is wrong.

It becomes more fatal after the mbuf refactor, more specificly, after
the commit 8f094a9ac5d7 ("mbuf: set mbuf fields while in pool"). The
refcnt resets to 1 after the last real reference. OTOH, it leads to a
situtation that we never know one mbuf is actually freed or not. This
would result the mbuf __just__ after the heading mbuf being freed twice:
it's firstly freed (and put back to mempool) when the underlaying PMD
finishes the DMA.  Later, it will then be freed again when vhost unpins
it. Meaning, one mbuf may be returned to the mempool twice, while in
turn, being allocated twice later. Something uncertain may happen then.
For example, the VM2VM case becomes broken.

the first 4 bytes of mbuf is buf_addr, with following 8 bytes for
buf_phyaddr. With below wrong definition, both buf_addr and lower
4 bytes buf_phyaddr are obtained to fill the virtqueue desc.

    Stopping ports...
    Checking link statuses...
    Port 0 Link Up - speed 10000 Mbps - full-duplex
    Done

The link status is queried by link_update callback when LSC is disabled.
Which in turn queries the "status" field.  However, the "status" is
read-only. I couldn't think of some proper ways to change the status
without doing device reset.

Instead of doing (the heavy) reset at stop, this patch introduced a flag,
which is set to 1 and 0 on start and stop, respectively. When it's set to
0, the link status is set to DOWN unconditionally.

4bf9e26d29 net/virtio-user: fix net status report
We only enabled LSC when using vhost-user as the backend, but it is
reported even when using vhost-kernel as the backend.

Fix it by only reportting LSC support when using vhost-user as the
backend.

bed3b24c87 net/virtio-user: fix feature negotiation
The feature negotiation in virtio-user is proven to be broken,
which results in device initialization failure.

Originally, we get features from vhost backend, and remove those
that are not supported. But when new feature is added, for example,
VIRTIO_NET_F_MTU, we fail to remove this new feature. Then, this
new feature will be negotiated, as both frontend and backend claim
to support this feature.

To fix it, we add a macro to record supported features, as a filter
to remove newly added features.

912be9daf4 net/vhost: stop dev in close and address mem leak
Move the call to stop the device inside the close routine because close
needs to stop the device if it isn't stopped.

Free the allocated queue buffers in close instead of doing so in remove.
Original code had these clean ups in remove which was causing memory
leak.

518208f3a1 net/virtio: fix queue notify
According to spec, we should write virtqueue index into the notify
address, rather than 1. Besides, some HW backend may rely on the data
written to identify which queue need to serve.
