[PATCH v2 00/15] Add driver for 1Gbe network chips from MUCSE

[Dong Yibo <dong100@mucse.com>]

Hi maintainers,

This patch series introduces support for MUCSE N500/N210 1Gbps Ethernet
controllers. Only basic tx/rx is included, more features can be added in
the future.

The driver has been tested on the following platform:
   - Kernel version: 6.16.0-rc3
   - Intel Xeon Processor

Changelog:
v1 -> v2: 
  [patch 01/15]:
  1. Fix changed section in MAINTAINERs file by mistake.
  2. Fix odd indentaition in 'drivers/net/ethernet/mucse/Kconfig'.
  3. Drop pointless driver version.
  4. Remove pr_info prints.
  5. Remove no need 'memset' for priv after alloc_etherdev_mq.
  6. Fix __ function names.
  7. Fix description errors from 'kdoc summry'.
  [patch 02/15]:
  1. Fix define by using the BIT() macro.
  2. Remove wrong 'void *' cast.
  3. Fix 'reverse Christmas tree' format for local variables.
  4. Fix description errors from 'kdoc summry'.
  [patch 03/15]:
  1. Remove inline functions in C files.
  2. Remove use s32, use int.
  3. Use iopoll to instead rolling own.
  4. Fix description errors from 'kdoc summry'.
  [patch 04/15]:
  1. Using __le32/__le16 in little endian define.
  2. Remove all defensive code.
  3. Remove pcie hotplug relative code.
  4. Fix 'replace one error code with another' error.
  5. Turn 'fw error code' to 'linux/POSIX error code'.
  6. Fix description errors from 'kdoc summry'.
  [patch 05/15]:
  1. Use iopoll to instead rolling own.
  2. Use 'linux/POSIX error code'.
  3. Use devlink to download flash.
  4. Fix description errors from 'kdoc summry'.
  [patch 06/15] - [patch 15/15]:
  1. Check errors similar to the patches [1-5].
  2. Fix description errors from 'kdoc summry'.
