[rbridge] Consensus Check: C-Tags

[Eastlake III Donald-LDE008]

Hi Dinesh,

I'm not sure exactly what you mean by "explicitly prohibit the use of
S-tags" but wherever the protocol spec requires a VLAN tag (Outer or
Inner), it currently specifies the use of the C-tag Ethertype. 

It is my impression that people are thinking that the current protocol
spec is for customer Rbridges and that, perhaps, at some point in the
future a separate "provider Rbridge" document could be written which
talks about S-tags, etc.

Thanks,
Donald

I'm fine with stating only about C-tags and not mention anything about 
S-tags. I wouldn't want the spec to explicitly prohibit the use of
S-tags.
