[c-nsp] QinQ termination on a Catalyst 6800

I have a distinct memory of running selective QinQ on a 6500a chassis a
couple of years back but there where some ASIC limit on it where the mapping
done on one interface would affect all ports in a portgroup belonging to
that specific ASIC. Perhaps this feature was removed because of this
limitation though?

Unfortunately, it's the same in 15.5, the only option for rewrite is to push
tags, and encapsulation supports only basic 802.1Q...
