[f-nsp] Support for tag-type on FESX?

[Stephen Wilcox]

(just to answer the previous emails - yes, this is the correct setup,
i have the right ports etc, i am not trying to encapsulate the
customer. consider that i may need a setup like that where i connect
with different devices or if i need to qinq through something in the
middle or if i want to vlan to a third party who cant use my tag-type)

Jorik,
 thanks I think the issue in question then is ability to 'translate'
although I am not sure why this is a feature since it seems to me that
getting the correct ethernet header in place should be part of the
basic switching capability!

I am using 05.1.00c - I am also wondering if this is fixed in later versions.

Anyone out there trying this tag translation with later versions?

Cheers
Steve
