[j-nsp] vlan-ccc between ACX5048 and EX4500

[Pavel Lunin]

Yes, EX4500/4550 chipset is not able to treat any additional tags of the
MPLS packet.

IIRC, they "officially support" (whatever it means) pseudowires and VPLS in
EX4550 to EX4550 mode only thus it's nowhere documented that it pops the
vlan tag by default and can't treat the control world.
