This series adds initial support for the ZTE DingHai Ethernet controller,
a high-performance PCIe Ethernet device supporting SR-IOV, hardware
offloading, and advanced virtualization features.

Changes from v3:
- Merged patches 1 and 2: 
  Combined initial framework with logging infrastructure
  for better code organization and reduced patch count. This was done because
  the logging infrastructure now uses Linux's built-in dev_err(), dev_info(),
  dev_warn(), etc. macros instead of a custom logging system.
- Removed unnecessary variable initialization: 
  Fixed "don't initialise variables".
- Fixed variable declaration order: 
  Applied "Reverse Christmas tree" ordering with variables
  declared from longest to shortest line length.
- Code quality improvements:
  Fixed all checkpatch.pl issues (alignment, formatting, etc.).

Changes from v2:
- Address maintainer feedback from v2 review:
  * Remove meaningless initialization
  * Change dh_pf_pci_table to static const for better encapsulation
  * Simplify MODULE_DESCRIPTION for brevity
- Coding style improvements:
  * Ensure all lines are within 80-column limit
  * Use kernel types (u32/u8) consistently throughout
  * Improve code readability with better formatting


Changes from v1 (addressing feedback from AndrewLunn):
- Update copyright years to 2022-2026
- Remove DRV_VERSION, MODULE_VERSION and related boilerplate
- Fix MODULE_AUTHOR to use person with email address
- Use module_pci_driver() instead of manual init/exit
- Remove empty suspend/resume callbacks
- Replace char priv[] flexible array with void *priv + kzalloc
- Switch logging from printk wrappers to dev_*() based macros
- Remove dh_helper.h and dh_log.c, simplify to dh_log.h only
- Fix variable declaration ordering (reverse Christmas tree)
- Remove unnecessary NULL check in remove and pf_dev=NULL in probe
- Fix indentation and remove unnecessary type casts
- Use kernel idiomatic "if (ret)" style

This is the initial submission and only includes the PF (Physical Function)
driver. The VF (Virtual Function) driver will be submitted separately.

  net/ethernet: add ZTE network driver support
  net/ethernet/zte/dinghai: add hardware register access and PCI
    capability scanning

A quick note: I've refined my email sending approach after the previous
series encountered some formatting issues. I've now tested the transmission
method and confirmed that the patches maintain proper formatting.
Thanks for your understanding!
