Add sriov_configure for ngbe and txgbe drivers.
Reallocate queue and irq resources when sriov is enabled.
Add wx_msg_task in interrupts handler, which is used to process the
configuration sent by vfs.
Add ping_vf for wx_pf to tell vfs about pf link change.
Do not add uAPIs for in these patches, since the legacy APIs ndo_set_vf_*
callbacks are considered frozen. And new apis are being replanned.

v6: https://lore.kernel.org/netdev/598334BC407FB6F6+20240804124841.71177-1-mengyuanlou@net-swift.com/
- Remove devlink allocation and PF/VF devlink port creation in these patches.
v5:
- 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.
v1: https://lore.kernel.org/netdev/DA3033FE3CCBBB84+20240307095755.7130-1-mengyuanlou@net-swift.com/
