A typical use case I would expect is the administrator on the PF wants
to set both the outer tag (S-VLAN) and inner tag (C-VLAN) of a VM.
It seems this only allows the administrator to set the outer tag but
does allow select type of the tag.
I am mostly interested because this is establishing a UAPI and we should
be sure it can handle future use cases. What about making the
ifla_vf_vlan struct handle multiple layers of headers, by passing a
nested list of {qos + vlan + vlan_proto} tuples for each vf.
Just curious does the hardware support the above S-VLAN + C-VLAN use
case as well?
Thanks,
John
