691ad36245 common/iavf: support VF with more than 16 queues
Currently there are limitations in the virthcnl.h interface that only
allow a maximum of 16 queues to be used by a VF driver. Add support in
virtchnl.h to allow a VF driver to request >16 queues. Also, the RSS
qregion size is currently assumed to be the max number of queues a VF
can request and/or is given on initialization. With larger VFs this
assumption can no longer be made, so add a new op to support querying
the max RSS qregion size.

In order to request more queues than the initially given queues the VF
driver needs to use the VIRTCHNL_OP_REQUEST_QUEUES opcode.

The VF is given more >16 queues it should use the new
VIRTCHNL_OP_GET_MAX_RSS_QREGION to determine its max qregion size. This
is needed to correctly configure the RSS LUT and/or configure filters
based on queue base/offset and queue region size.

If the VF is configuring >16 queues it should use the following opcodes
to configure the qeueus and interrupts after successfully requesting
them.

VIRTCHNL_OP_MAP_QUEUE_VECTOR
VIRTCHNL_OP_ENABLE_QUEUES_V2
VIRTCHNL_OP_DISABLE_QUEUES_V2

Also, add support in virtchnl_vc_validate_vf_msg() to validate the above
messages. As a part of this move the virtchnl_vector_limits enumeration
directly above the function it's used.

The patch also update base code release version in readme.

3ba2e519ea common/dpaax/caamflib: support PDCP-SDAP
The SDAP is a protocol in the LTE stack on top of PDCP. It is
dedicated to QoS.

The difficulty of implementing this protocol is because the
PDCP change behavior regarding encryption and authentication
of the SDU it receives. In effect PDCP shall not encrypt the
SDAP SDU but must authenticate it (when encryption and
authentication is enabled).

The current version of SEC does not support the SDAP and the
change of behavior of PDCP prevent the use of the PDCP
protocol command available.

The way to do it is to reuse the PDCP implementation but to
not use the PDCP protocol and to have descriptors which
performs the PDCP protocol.

It is implemented by doing small changes of code:
        #ifdef SDAP_SUPPORT
                length += SDAP_BYTE_SIZE;
                offset -= SDAP_BYTE_SIZE;
        #endif
after having computed the size of the SN to read from the
input data, then
        #ifdef SDAP_SUPPORT
                MATHI(p, MATH0, LSHIFT, 8, MATH1, 8, 0);
                MATHB(p, MATH1, AND, sn_mask, MATH1, 8, IFB | IMMED2);
        #else
                MATHB(p, MATH0, AND, sn_mask, MATH1, 8, IFB | IMMED2);
        #endif
It will keep the SN and the SDAP header in MATH0, then shift
it to remove the SDAP header and store the result in MATH1.

e9b9739264 config: remap flags used for Arm platforms
RTE_ARCH_xx flags are used to distinguish platform architectures.
These flags can be used to pick different code paths for different
architectures at compile time.
For Arm platforms, there are 3 flags in use: RTE_ARCH_ARM,
RTE_ARCH_ARMv7 and RTE_ARCH_ARM64.
RTE_ARCH_ARM64 is for 64-bit aarch64 platforms,
and RTE_ARCH_ARM & RTE_ARCH_ARMv7 are for 32-bit platforms.
RTE_ARCH_ARMv7 is for ARMv7 platforms as its name suggested.

The issue is meaning of RTE_ARCH_ARM is not clear enough.
Because no info about platform word length is included in the name.
To make the flag names more clear, a naming scheme is proposed.

RTE_ARCH_ARM (all Arm platforms)
    |
    +----RTE_ARCH_32 (New. 32-bit platforms of all architectures)
    |        |
    |        +----RTE_ARCH_ARMv7 (ARMv7 platforms)
    |        |
    |        +----RTE_ARCH_ARMv8_AARCH32 (aarch32 state on aarch64 machine)
    |
    +----RTE_ARCH_64 (64-bit platforms of all architectures)
             |
             +----RTE_ARCH_ARM64 (64-bit Arm platforms)

RTE_ARCH_32 will be explicitly defined for 32-bit platforms.

To fit into the new naming scheme, current usage of RTE_ARCH_ARM in
project is mapped to (RTE_ARCH_ARM && RTE_ARCH_32).

Matching flags for other architectures are:
RTE_ARCH_X86
    |
    +----RTE_ARCH_32
    |        |
    |        +----RTE_ARCH_I686
    |        |
    |        +----RTE_ARCH_X86_X32
    |
    +----RTE_ARCH_64
             |
             +----RTE_ARCH_X86_64

RTE_ARCH_PPC_64 ---- RTE_ARCH_64

On tunnel reconfiguration added and removed entries become busy to

removed entries are purged from the table.

0e16872572 common/sfc_efx/base: add efsys API to find a memory BAR
Function control window lookup needs memory BARs handles to
search Xilinx capabilities tables.

Define an API to get a memory BAR handle by a PCIe device handle and
BAR index.

a45edfce34 common/sfc_efx/base: add function control window lookup API
Riverhead NIC may provide a locator of function control window
(EF100 resource locator).
The locator may be present in a Xilinx capabilities table which
itself is located by looking into extended PCI capabilities.

PCI capabilities are made possible to access by adding PCI config
space interface to efsys.

APIs are implemented to facilitate function control window lookup:
 - API to find an extended PCI capability given a capability ID;
 - API to read Xilinx PCI capability;

341bd4e07d common/sfc_efx/base: add function control window concept
Function control window can be located at a different offset than
other windows on Riverhead. Meaning that the drivers must handle
accesses to the function control window differently in case of EF100.

Add accessor macros for function control window and change
EFX NIC create API to facilitate that accessors.

c1f0218900 common/sfc_efx/base: choose smallest Rx prefix on Riverhead
Riverhead supports many Rx prefixes. The Rx prefix may be chosen
based on which information is required.

To have better performance choose the smallest Rx prefix which
meets our requirements.

Right now there is no way to specify requirements on Rx queue
creation, but it could be added in the future.

addition of one more argument.
Non essential parameters not supported in some cases are moved
into helper structure.
