This is the 1/3 patch of the patch-set described below.

The patch-set contains driver for Huawei's 3rd generation HiNIC
Ethernet device that will be available in the future.

This is an SRIOV device, designed for data centers.
Initially, the driver only supports VFs.

Following the discussion over RFC01, the code will be submitted in
separate smaller patches where until the last patch the driver is
non-functional. The RFC02 submission contains overall view of the entire
driver but every patch will be posted as a standalone submission.

Changes:

RFC V01: https://lore.kernel.org/netdev/cover.1730290527.git.gur.stavi@huawei.com

RFC V02: https://lore.kernel.org/netdev/cover.1733990727.git.gur.stavi@huawei.com
* Reduce overall line of code by removing optional functionality.
* Break down into smaller patches.

PATCH 01 V01: https://lore.kernel.org/netdev/cover.1734599672.git.gur.stavi@huawei.com
* Documentation style and consistency fixes (from Bjorn Helgaas)
* Use ipoll instead of custom code (from Andrew Lunn)
* Move dev_set_drvdata up in initialization order (from Andrew Lunn)
* Use netdev's max_mtu, min_mtu (from Andrew Lunn)
* Fix variable 'xxx' set but not used warnings (from Linux patchwork)

PATCH 01 V02: https://lore.kernel.org/netdev/cover.1735206602.git.gur.stavi@huawei.com
* Add comment regarding usage of random MAC. (Andrew Lunn)
* Add COMPILE_TEST to Kconfig (Jakub Kicinski)

PATCH 01 V03: https://lore.kernel.org/netdev/cover.1735735608.git.gur.stavi@huawei.com
* Rephrase Kconfig comment (Jakub Kicinski)
* Kconfig: add 'select AUXILIARY_BUS' (Kernel test robot)
* ARCH=um: missing include 'net/ip6_checksum.h' (Kernel test robot)

PATCH 01 V04:
* Improve naming consistency, missing hinic3 prefixes (Suman Ghosh)
* Change hinic3_remove_func to void (Suman Ghosh)
* Add adev_event_unregister (Suman Ghosh)
* Add comment for service types enum (Suman Ghosh)
