[PATCH rdma v4 0/2] Add ZTE DingHai Ethernet Protocol Driver for RDMA

[Yanze Zhang]

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

Changes in v4:
- Fixed Kconfig help text indentation (Julian Braha).
- Self-correction: Updated SPDX license tag and fixed Makefile
  indentation to strictly follow subsystem standards.

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- Removed outdated reference to "auxiliary bus following hns pattern" from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).
