[c-nsp] 7600 layer 2 local switching: EVC to SVI

[Tassos Chatzithomaoglou]

Similar to this case, is there a way (or any future plans) to connect an EVC directly to a 
VFI?
Currently i'm using EVC => SVI => VFI, but i would like to avoid the intermediate step, 
something that ASR9k can already do.
