I'm aware of several issues of vge(4) but I haven't had time to
dig into yet. Newer generations of PCIe VT613x chips also
complicates the work. I'm not sure when I have spare time to work
on vge(4) but it's one of item in my TODO. 

Basically you may have to fix bus_dma(9) and PHY handling in vge(4)
and it would require a lot of work.
