[c-nsp] 6704 again

[MKS]

Hi list

I have been trying to read about the limitations of the 6704 card. I
have a case where we need to double up in the interfaces using this
card.
So one port-channel facing the access (2x10G) and 2x10G mpls to a P
node (just individual links, no port-channel)

In this case, does it matter what ports I use for the port-channel?
Does it matter if the card is CFC or DFC?

Regards
MKS
