To align with review comments, the patch series [v1] introducing RDMA
RoCEv2 support for the Intel Infrastructure Processing Unit (IPU) E2000
line of products is going to be submitted in three parts:

1. Modify ice to use specific and common IIDC definitions and
   pass a core device info to irdma.

2. Add RDMA support to idpf and modify idpf to use specific and
   common IIDC definitions and pass a core device info to irdma.

3. Add RDMA RoCEv2 support for the E2000 products, referred to as
   GEN3 to irdma.

This first part is a 5 patch series based on the original
"iidc/ice/irdma: Update IDC to support multiple consumers" patch
to allow for multiple CORE PCI drivers, using the auxbus.

Patches:
1) Move header file to new name for clarity and replace ice
   specific DSCP define with a kernel equivalent one in irdma
2) Unify naming convention
3) Separate header file into common and driver specific info
4) Replace ice specific DSCP define with a kernel equivalent
   one in ice
5) Implement core device info struct and update drivers to use it

This patch series is based on v6.15-rc1.

Changelog:

V4 to V5 changes:

- Use exported symbols instead of a device ops struct
- Rename the IDC header file iidc.h to iidc_rdma.h
- Move ice specific functionality to iidc_rdma_ice.h
- Use iidc_* naming convention
- Replace ice specific DSCP define with a kernel equivalent one

V3 to V4 changes:

- Split up the patch series [v3] into three parts and
  send out independently the ice/iidc related changes patch -
  "iidc/ice/irdma: Update IDC to support multiple consumers"
