nvethernet: Update status counters using ioctls

Browse Source 
Issue:
TSN, extra, packet error stats counters
are not getting updated during virtualization,
as NVEQOS reads them from the VF OSI core structure.

Fix:
Add new ioctls to update these counters from
the ethernet server OSI core to
the VF OSI core structure.

Bug 3763499
