Subject: [PATCH net-next v4 0/6] add sriov support for wangxun NICs

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 v4:
- Simon Horman
Move wx_ping_vf to patch 6.
Modify return section format in Kernel docs.
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.
