[PATCH rdma v3 0/2] Add ZTE DingHai Ethernet Protocol Driver for RDMA

[Yanze Zhang]

Hi maintainers and reviewers,

This is v3 of the ZTE DingHai (ZXDH) RDMA driver submission.
Thank you Junxian Zhuang and Julian Braha for your reviews on v1.

Note: Both reviewers provided feedback exclusively on v1. Since v2 received
no additional comments, this v3 applies all v1 feedback directly onto the
v2 codebase. The changes below are relative to v2.

Changes in v3:
- Fixed missing handle release in zxdh_remove() as pointed out by Junxian
  on v1.
- Removed outdated reference to "auxiliary bus following hns pattern" from
  cover letter description (this was already corrected in v2; re-stating
  here since Junxian's comment was on v1).
- Addressed Junxian's indentation concern on v1: I verified the code against
  checkpatch.pl --strict and confirmed 8-character indentation is used
  throughout. This v3 was sent using a different email client/format to rule
  out MUA-induced formatting corruption. If the indentation still appears
  incorrect in your viewer, please review the updated series and let me know
  if the issue persists.

Changes in v2:
- Removed redundant 'depends on INFINIBAND' from Kconfig as it is already
  wrapped by the parent if-block (Julian Braha, v1 review).

The driver provides RoCEv2 support for ZTE DingHai network adapters and has
been tested with perftest and rping utilities.

Best regards,
Yanze Zhang
