What I meant by that comment was - yes you can use QinQ with the same
SVLAN and CVLAN tags but you can only have that combination once per
interface. All the other scenarios of changing SVLANs or CVLANs or
changing both S&CVLANs allows for differentiating between subscribers
or services. There isn't much poing in usnig QinQ just to use the same
S&CVLAN on an interface. You limit your self :)

Cheers,
James.
