So I applied this patch (basically just disabling vlan stripping for VFs)
and vlan-on-vf to vlan-on-vf communication now seems to be working.

This is with igb-4.0.17 and igbvf-2.0.4.  Without the patch, it seems
like something isn't being handled right on the rx side and it's not
treated as a vlan packet.
