[f-nsp] Transparent VLL between XMR and Juniper T-series

[David Ball]

  Thanks for the great suggestions.  I tried setting the tag type manually and things worked great for both tagged or untagged.  
   That said, I have to think that there's a non-kludgy (please pardon the expression) way of doing this though, no ?  I mean, how do folks deliver Transparent Lan Services to their customers?
  I'll use the 'tag-type' workaround if I must..........but must I ?  I've tried 'raw-mode' with untagged endpoints, which works great for untagged, but as soon as it's tagged, it only works in 1 direction (from Juniper to XMR, not the other way around).  the MTU is 1500, but the test set is generating 1280 frames, so MTU shouldn't be hindering it...

vll xmrtop-t640-vll 500 raw-mode
  vll-peer 172.16.0.1
  untag e 2/11
