> Add ping_vf for wx_pf to tell vfs about pf link change.

> v9:
> - Using FIELD_{GET,PREP} macros makes the code more readable.
> - Add support for the new mac_type aml in the configuration flow.
> v8: https://lore.kernel.org/netdev/20250309154252.79234-1-mengyuanlou@net-swift.com/
> - Request a separate processing function when ngbe num_vfs is equal to 7.
> - Add the comment explains why pf needs to reuse interrupt 0 when the ngbe
> num_vfs equals 7.
> - Remove some useless api version checks because vf will not send commands
> higher than its own api version.
> - Fix some code syntax and logic errors.
> v7: https://lore.kernel.org/netdev/20250206103750.36064-1-mengyuanlou@net-swift.com/
> - Use pci_sriov_set_totalvfs instead of checking the limit manually.
> v6: https://lore.kernel.org/netdev/20250110102705.21846-1-mengyuanlou@net-swift.com/
> - Remove devlink allocation and PF/VF devlink port creation in these patches.
> v5: https://lore.kernel.org/netdev/598334BC407FB6F6+20240804124841.71177-1-mengyuanlou@net-swift.com/
> - Add devlink allocation which will be used to add uAPI.
> - Remove unused EXPORT_SYMBOL.
> - Unify some functions return styles in patch 1/4.
> - Make the code line less than 80 columns.
> v4: https://lore.kernel.org/netdev/3601E5DE87D2BC4F+20240604155850.51983-1-mengyuanlou@net-swift.com/
> - Move wx_ping_vf to patch 6.
> - Modify return section format in Kernel docs.
> v3: https://lore.kernel.org/netdev/587FAB7876D85676+20240415110225.75132-1-mengyuanlou@net-swift.com/
> - Do not accept any new implementations of the old SR-IOV API.
> - So remove ndo_vf_xxx in these patches. Switch mode ops will be added
> - in vf driver which will be submitted later.
> v2: https://lore.kernel.org/netdev/EF19E603F7CCA7B9+20240403092714.3027-1-mengyuanlou@net-swift.com/
> - Fix some used uninitialised.
> - Use poll + yield with delay instead of busy poll of 10 times in mbx_lock obtain.
> - Split msg_task and flow into separate patches.
