Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for
array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).
As found with Coccinelle[1], add __counted_by for struct i40e_qvlist_info.

The ice driver provides QoS information to auxiliary drivers
through the exported function ice_get_qos_params. This function
doesn't currently support L3 DSCP QoS.
Add the necessary defines, structure elements and code to support
DSCP QoS through the IIDC functions.

Allow support for 'enable_iwarp' and 'enable_roce' devlink params to turn
on/off iWARP or RoCE protocol support for E800 devices.
For example, a user can turn on iWARP functionality with,
devlink dev param set pci/0000:07:00.0 name enable_iwarp value true cmode runtime
This add an iWARP auxiliary rdma device, ice.iwarp.<>, under this PF.
A user request to enable both iWARP and RoCE under the same PF is rejected
since this device does not support both protocols simultaneously on the
same port.

Add Kconfig and Makefile to build irdma driver.
Remove i40iw driver and add an alias in irdma.
Remove legacy exported symbols i40e_register_client
and i40e_unregister_client from i40e as they are no
longer used.
irdma is the replacement driver that supports X722.

Add the definitions to the i40e client header file in
preparation to convert i40e to use the new auxiliary bus
infrastructure. This header is shared between the 'i40e'
Intel networking driver providing RDMA support and the
'irdma' driver.

There is a regular need in the kernel to provide a way to declare having a
dynamically sized set of trailing elements in a structure. Kernel code
should always use “flexible array members”[1] for these cases. The older
style of one-element or zero-length arrays should no longer be used[2].
Refactor the code according to the use of a flexible-array member in struct
i40e_qvlist_info instead of one-element array, and use the struct_size()
helper.
