There seems to be a "l2protocol-tunnel <proto>" interface config
command, but it's only for switchports.

As I have understood the way the PFC does EoMPLS port-mode, it simply
forwards any incoming frame without discrimination. It should (AFAIK)
not discern between data, CDP, UDLD, STP or whatever.

It sure does sound like a bug, an SXI2 specific bug. We currently don't
have any available switches to test anything on, though I would've like
to see if I could reproduce.
