[f-nsp] l2 pseudowire with between ASNs

Hi Chip,
Brocade doesn't support "send-label" (at least not for IPv4 - it is there for IPv6 to support 6PE). "next-hop-mpls" is a different thing. It shouldn't have any affect on pseudowires.
If do you have LDP working, you will probably need to set raw mode on the VLL to match the VC type with the Cisco.
Cheers.
Mitchell
