Add XDP support to hv_netvsc driver

[Joseph Salisbury]

Microsoft would like to request the following three patches in all releases supported on Azure:

351e1581395fc (“hv_netvsc: Add XDP support”)
12fa74383ed4d (“hv_netvsc: Update document for XDP support”)
184367dce4f7 (“hv_netvsc: Fix XDP refcnt for synthetic and VF NICs”)

These patches add support of XDP in native mode to the hv_netvsc driver, and
transparently sets the XDP program on the associated VF NIC as well.
