Hi,

This patch series adds control path verbs support for the bng_re
driver, along with the corresponding bnge driver changes it depends
on.

Fast path verbs depend on a specific HW resource configuration in the
bnge driver, and work on that is in progress. We plan to submit fast path
verbs support in a follow-up series once the dependent changes in bnge
are pushed and available in the rdma repo.

The corresponding rdma-core user space library patches will also be
published shortly.

1) bnge: MPC infrastructure change
2) bnge: Update New HSI
3) bnge: MPC ring reservation change
4) bng_re: Add RoCE MPC infrastructure and xid manager 
5) bng_re: Add support verbs
6) bng_re: Add ucontext/mmap verbs
7) bng_re: Add GID verbs
8) bng_re: Add PD verbs
9) bng_re: Add MR verbs
10) bng_re: Add CQ control path verbs
11) bng_re: Add SRQ control path verbs
12) bng_re: Add statistics verbs
13) bng_re: Add AH verbs
14) bng_re: Add QP control path verbs
15) bng_re: Register device operations with ib-core

Thanks,
Siva

The series has received plenty of comments from Sahiko. Please address
them first:
https://sashiko.dev/#/patchset/20260904104328.763768-1-siva.kallam@broadcom.com

There is little appetite for accepting this series only to be flooded
with AI-generated fixes afterwards.

Thanks
