d112a3ecb7 net/sfc: fix Tx reap behaviour on port stop on EF10 datapath
Tx reap mechanism on EF10 native datapath was altered by one
of the recent patches to introduce performance optimisations
using the common technique of freeing mbuf segments in bulks.

From this perspective, the way of associating SW descriptors
with individual mbuf segments rather than with whole packets
was adopted as a key requirement for the entire optimisation.

However, only the fast path reap function was amended to fit
the new scheme whilst the corresponding function on the port
stop path was left intact by mistake. This implies incorrect
usage of rte_pktmbuf_free() with regard to separate segments
rather than calling rte_pktmbuf_free_seg() and must be fixed.

89ee1e94bc mempool/octeontx: move mbox from event to mempool
Octeontx mempool pmd need mailbox for pool setup.
That mailbox was defined at drivers/event/octeontx.
So mempool has dependency on event/octeontx driver and
commit:8700239f7767 has added make rule which makes sure event/*
get build before mempool, but this rule introduces
cyclic dependency and may create problem to future
feature addition in drivers/Makefile.

Same problem noticed and reported in below thread:
http://dpdk.org/ml/archives/dev/2017-October/079187.html

The patch solves problem by moving mbox definition from
drivers/event/octeontx to drivers/mempool/octeontx.
Moving mbox files involves below changes:

* Renamed ssovf_mbox.[ch] --> octeontx_mbox.[ch]
* Renamed ssovf_probe.c  --> octeontx_ssovf.c
* Introduced pool logger file.
* Moved API from rte_pmd_octeontx_ssovf_version.map to
  rte_mempool_octeontx_version.map.
* Respective Makefile changes done in
  drivers/event/octeontx/Makefile and drivers/mempool/octeontx/Makefile.

power of two; extra queues are silently discarded. This does not prevent

078b8b452e net/mlx4: add RSS flow rule action support
This patch dissociates single-queue indirection tables and hash QP objects
from Rx queue structures to relinquish their control to users through the
RSS flow rule action, while simultaneously allowing multiple queues to be
associated with RSS contexts.

Flow rules share identical RSS contexts (hashed fields, hash key, target
queues) to save on memory and other resources. The trade-off is some added
complexity due to reference counters management on RSS contexts.

The QUEUE action is re-implemented on top of an automatically-generated
single-queue RSS context.

The following hardware limitations apply to RSS contexts:

- The number of queues in a group must be a power of two.
- Queue indices must be consecutive, for instance the [0 1 2 3] set is
  allowed, however [3 2 1 0], [0 2 1 3] and [0 0 1 1 2 3 3 3] are not.
- The first queue of a group must be aligned to a multiple of the context
  size, e.g. if queues [0 1 2 3 4] are defined globally, allowed group
  combinations are [0 1] and [2 3]; groups [1 2] and [3 4] are not
  supported.
- RSS hash key, while configurable per context, must be exactly 40 bytes
  long.
- The only supported hash algorithm is Toeplitz.

fc4e66649a net/mlx4: convert Rx path to work queues
Work queues (WQs) are lower-level than standard queue pairs (QPs). They are
dedicated to one traffic direction and have to be used in conjunction with
indirection tables and special "hash" QPs to get the same level of
functionality.

These extra objects however are the building blocks for RSS support brought
by subsequent commits, as a single "hash" QP can manage several WQs through
an indirection table according to a hash algorithm and other parameters.

c64c58adc0 net/mlx4: allocate queues and mbuf rings together
Since live Tx and Rx queues cannot be reused anymore without being
destroyed first, mbuf ring sizes are fixed and known from the start.

This allows a single allocation for queue data structures and mbuf ring
together, saving space and bringing them closer in memory.

7977082649 net/mlx4: drop live queue reconfiguration support
DPDK ensures that setup functions are never called on configured queues,
or only if they have previously been released.

PMDs therefore do not need to deal with the unexpected reconfiguration of
live queues which may fail with no easy way to recover. Dropping support
for this scenario greatly simplifies the code as allocation and setup steps
and checks can be merged.

c8912bec52 net/mlx4: fix invalid errno value sign
Tx queue elements allocation function sets rte_errno properly and returns
its negative version. Reassigning this value to rte_errno is thus both
invalid and unnecessary.

67e6cce675 net/mlx4: update Rx/Tx callbacks consistently
Although their "removed" version acts as a safety against unexpected bursts
while queues are being modified by the control path, these callbacks are
set per device instead of per queue. It makes sense to update them during
start/stop/close cycles instead of queue setup.

As a side effect, this commit addresses a bug left over from a prior
commit: bringing the link down causes the "removed" Tx callback to be used,
however the normal callback is not restored when bringing it back up,
preventing the application from sending traffic at all.

Updating callbacks for a link change is not necessary as bringing the
netdevice down is normally enough to prevent traffic from flowing in.

3e49f870c5 net/mlx4: add flow support for multicast traffic
Give users the ability to create flow rules that match all multicast
traffic. Like promiscuous flow rules, they come with restrictions such as
not allowing additional matching criteria.
