Message

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.

changes v3:
- Jakub Kicinski
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.
changes v2:
- Simon Horman:
Fix some used uninitialised.
- Sunil:
Use poll + yield with delay instead of busy poll of 10 times
in mbx_lock obtain.
Split ndo_vf_xxx , msg_task and flow into separate patches.

Hi Mengyuan Lou,

Thanks for your updated patch-set.

Unfortunately net-next is currently closed for the v6.10 merge window.
Please consider reposting as a PATCH once net-next re-opens, after 27th May.

In the meantime, feel free to post new versions as you get feedback,
but please switch to posting as RFC during that time.

Link: https://docs.kernel.org/process/maintainer-netdev.html

Also, please be sure to seed the CC list of your patch submissions
using the output of get-maintainers.pl PATCH. b4 can also be of
assistance here.
