The max vlan tags that can be offloaded is 2, including any upstream VLAN aggregator. Currently there is no way for the net driver to know whether the upstream vswitch (if any) is using vlan tags, so there is no way to know how many tags we can request. Along with the implementation for the ndo_set_vf_vlan callback, this patch also adds 2 VLAN tags for the driver created VEB switch if possible, that way it is possible to offload as many tags as are allowed.
