This patch introduces the new framework to share common code between
the SW crypto PMDs that depend on the intel-ipsec-mb library.
This change helps to reduce future effort on the code maintenance and
feature updates.
The PMDs that will be added to this framework in subsequent patches are:
- AESNI MB
- AESNI GCM
- CHACHA20_POLY1305
- KASUMI
- SNOW3G
- ZUC
The use of these PMDs will not change, they will still be supported for
x86, and will use the same EAL args as before.
The minimum required version for the intel-ipsec-mb library is now v1.0.

link bounding auto-test internally creates emulated ethdev.
Some tests change Rx/Tx functions of this emulated device on the fly:
by directly modifying rte_eth_dev fields and without doing stop/start

As now ethdev uses rte_eth_fp_ops[] for fast-path functions, these
direct changes doesn't make expected effect.
Fix the problem by guarding fast-path functions changes with

Commit 1bb4a528c4 ("ethdev: fix max Rx packet length") clarified the
expected usage of the max_rx_pktlen and max_mtu values and implemented
some extra checks on these values to ensure they are sane. After this,
the AF_XDP PMD fails to initialise. The value for max_rx_pktlen which
represents the max size of the Ethernet frame was set to ETH_FRAME_LEN
(1514) and the max_mtu which represents the size of the payload was set
to the max size of the Ethernet frame. This did not make sense, as
naturally the maximum frame size should be greater than the payload
size.
Fix this by setting the max_rx_pktlen equal to the max size of the
Ethernet frame as expected, and the max MTU equal to the max_rx_pktlen
less the overhead which is set to the size of an Ethernet header plus
CRC.

Current, the max waiting time for MBX response is 500ms, but in
some scenarios, it is not enough. Since it depends on the response
of the kernel mode driver, and its response time is related to the
scheduling of the system. In this special scenario, most of the
cores are isolated, and only a few cores are used for system
scheduling. When a large number of services are started, the
scheduling of the system will be very busy, and the reply of the

to fail.
This patch add a runtime config to set the max wait time. For the

In current DPDK framework, each Rx queue is pre-loaded with mbufs to
save incoming packets. For some PMDs, when number of representors scale
out in a switch domain, the memory consumption became significant.
Polling all ports also leads to high cache miss, high latency and low
throughput.
This patch introduces shared Rx queue. Ports in same Rx domain and
switch domain could share Rx queue set by specifying non-zero sharing
group in Rx queue configuration.
Shared Rx queue is identified by share_rxq field of Rx queue
configuration. Port A RxQ X can share RxQ with Port B RxQ Y by using
same shared Rx queue ID.
No special API is defined to receive packets from shared Rx queue.
Polling any member port of a shared Rx queue receives packets of that
queue for all member ports, port_id is identified by mbuf->port. PMD is
responsible to resolve shared Rx queue from device and queue data.
Shared Rx queue must be polled in same thread or core, polling a queue
ID of any member port is essentially same.
Multiple share groups are supported. PMD should support mixed
configuration by allowing multiple share groups and non-shared Rx queue
on one port.
Example grouping and polling model to reflect service priority:
Group1, 2 shared Rx queues per port: PF, rep0, rep1
Group2, 1 shared Rx queue per port: rep2, rep3, ... rep127
Core0: poll PF queue0
Core1: poll PF queue1
Core2: poll rep2 queue0
PMD advertise shared Rx queue capability via RTE_ETH_DEV_CAPA_RXQ_SHARE.
PMD is responsible for shared Rx queue consistency checks to avoid
member port's configuration contradict each other.

Currently, if we map a memory area A, then map a separate memory area B
that by coincidence happens to be adjacent to A, current implementation
will merge these two segments into one, and if partial unmapping is not
supported, these segments will then be only allowed to be unmapped in
one go. In other words, given segments A and B that are adjacent, it
is currently not possible to map A, then map B, then unmap A.
Fix this by adding a notion of "chunk size", which will allow
subdividing segments into equally sized segments whenever we are dealing
with an IOMMU that does not support partial unmapping. With this change,
we will still be able to merge adjacent segments, but only if they are
of the same size. If we keep with our above example, adjacent segments A
and B will be stored as separate segments if they are of different
sizes.

Previously, we set txq affinity to 0 and let firmware
to perform round-robin when bonding. Firmware uses a
global counter to assign txq affinity to different
physical ports accord to remainder after division.
There are three dis-advantages:
1. The global counter is shared between kernel and dpdk.
2. After restarting pmd or port, the previous counter value
is reused, so the new affinity is unpredictable.
3. There is no way to get what affinity is set by firmware.
In this update, we will create several TISs up to the
number of bonding ports and bind each TIS to one PF port.
For each port, it will start to pick up TIS using its port
index. Upper layer application can quickly calculate each txq's
affinity without querying.
At DPDK layer, when creating txq with 2 bonding ports, the
affinity is set like:
port 0: 1-->2-->1-->2
port 1: 2-->1-->2-->1
port 2: 1-->2-->1-->2

While creating Send Queue (SQ) object with Verbs API, the PMD assigned

FDB domain, to redirect egress traffic from the queue being created to

With DevX API there is no IB-device port attribute (it is merely kernel

in FDB explicitly. PMD did not provide this and using DevX API for
E-Switch configurations was disabled.
The default miss FDB flow matches E-Switch manager vport (to make sure
the source is some representor) and SQn (Send Queue number - device
internal queue index). The root flow table managed by kernel/firmware
and it does not support vport redirect action, we have to split the
default miss flow into two ones:
