Merge branch 'add-vf-drivers-for-wangxun-virtual-functions' 

Mengyuan Lou says:

====================
Add vf drivers for wangxun virtual functions

Introduces basic support for Wangxun’s virtual function (VF) network
drivers, specifically txgbevf and ngbevf. These drivers provide SR-IOV
VF functionality for Wangxun 10/25/40G network devices.
The first three patches add common APIs for Wangxun VF drivers, including
mailbox communication and shared initialization logic.These abstractions
are placed in libwx to reduce duplication across VF drivers.
Patches 4–8 introduce the txgbevf driver, including:
PCI device initialization, Hardware reset, Interrupt setup, Rx/Tx datapath
implementation and link status changeing flow.
Patches 9–12 implement the ngbevf driver, mirroring the functionality
added in txgbevf.
