In quagga-ldp, the ldpd daemon issued label operations directly to the
kernel.  In quagga-mpls, label operations are sent via the zserve API and
the zebra daemon then issues them to the kernel.

Yes.

quagga-mpls" code?

The only reason you will need to run on a mpls enabled kernel is
if you want to test the data path.  I think there are still a couple of
significant bugs that will prevent us from getting that far, so at this=20
point I don't think you _need_ to run an mpls enabled kernel.
