Log message:
VPLS signaling support.
This patch introduces full support for pseudowire signaling in ldpd(8),
including Control Word and Status TLV negotiation.
As of now it's not possible to configure a VPWS, but the signaling is
the same. In the future, when VPWS support is available in the kernel,
ldpd(8) can be extended to support VPWS with only a few modifications.
Limitations:
* No support for FEC 129, only FEC 128 (more widely deployed);
* No support for group withdraws (not widely deployed);
* No support for MAC withdraws (not widely deployed).
