43f3f05fb6 net/octeontx2: support dynamic topology update
Modify resource allocation and freeing logic to support
dynamic topology commit while to traffic is flowing.
This patch also modifies SQ flush to timeout based on minimum shaper
rate configured. SQ flush is further split to pre/post
functions to adhere to HW spec of 96XX C0.

89fc6763b1 common/octeontx2: support C0 silicon version
Avoid using PCI subsystem device id for SoC revision
identification and just use PCI revision id to support C0 silicon.
This patch also reduces SQB threshold to 70% to have
sufficient buffer before we overflow SQ.

c261680cdb net/octeontx2: support SDP interface
System DPI Packet Interface Unit (SDP) is a co-processor
of OCTEON TX2 which provides PCIe endpoint support for a
remote host to DMA packets into and out of the OCTEON TX2 SoC.
SDP interface comes in to live only when it is connected in
EP mode. It exposes input and output queue pairs to remote host
for instruction input and packet output. It can be used as
a communication channel between remote host and OCTEON TX2.
Host machine needs to use corresponding user/kernel mode
driver to communicate with SDP interface on OCTEON TX2 SoC.

SDP interface support is limited to SDP PF device now.
No SDP VF support.

8d0715f054 net/octeontx2: support 96xx A1 silicon revision
Update workaround changes for erratas that are fixed on 96xx A1.
This patch also enables cq drop for all the passes for
maintaining performance along with updating a default
Rx ring size in dev_info.

d1d823e7a8 common/octeontx2: support CNF95xx SoC
Update platform support of CNF95xx in documentation and
also, update the HW cap based on PCI subsystem id and revision id.
This patch also changes HW capability handling to be based on
PCI Revision ID. PCI Revision ID contains a unique identifier
to identify chip, major and minor revisions.

b6288e236e drivers: add init and fini on octeontx2 NPA object
NPA object needs to initialize memory for queue interrupts context,
pool resource management, etc. This patch adds support for initializing
and finalizing the NPA object.

This patch also updates the otx2_npa_lf definition to meet the init/fini
requirements.

05a58afca1 common/octeontx2: add uplink message support
The events like PHY link status change by AF or PHY configuration
change by PF would call for the uplink message.
The AF initiated uplink would land it in PF and PF would further
forward to VF(if it is intended for that specific VF)

The PF initiated uplink would be distributed to all active VFs.
This patch adds support for the same.

0e9734fe41 common/octeontx2: handle intra device operations
The mempool device(NPA) may be provisioned as a standalone device or
it can be part of ethdev/eventdev device. In order to address
mempool as standalone or integrated with ethdev/eventdev device,
An intra device structure being introduced.

When the _first_ ethdev/eventdev PCIe device or standalone mempool(NPA)
devices get probed by the eal PCI subsystem,
The NPA object(struct otx2_npa_lf) stored in otx2_dev base class.
Once it is accomplished, the other consumer drivers like
ethdev driver or eventdev driver use otx2_npa_* API to operate on
shared NPA object.

The similar concept followed for SSO object, Which needs to share between
PCIe devices.

e1d9a02ad8 common/octeontx2: introduce common device class
Introduce otx2_dev class to hold octeontx2 PCIe device specific
information and operations.

All PCIe drivers(ethdev, mempool, cryptodev and eventdev) in octeontx2,
inherits this base object to avail the common functionalities such
as mailbox creation, interrupt registration, etc of the PCIe device.
