To align with review comments, the patch series [1] introducing RDMA RoCEv2 support for the Intel Infrastructure Processing Unit (IPU) E2000 line of products is going to be submitted in three parts: 1. Allow for multiple consumers in the Inter-Driver Communication (IDC) interface and modify ice to use the generalized IDC definitions. 2. Adapt idpf to the IDC definitions and add RDMA support to idpf. 3. Add RDMA RoCEv2 support for the E2000 products, referred to as GEN3 in irdma. This first part is a single patch - "iidc/ice/irdma: Update IDC to support multiple consumers" which allows for multiple consumers using auxiliary bus, implementing an "ops" struct and core_dev_info struct. This patch is based on v6.14-rc1.
