RFC1483. We are more concerened with the payload than the header.
What if the payload is, for example, LANE, rather than RFC 1483?

Geez, you won't the ATM encapsulation issue die will you :) I was reluctant to turn an experiment into the default behaviour, however it seems to work, so here is a patch to make PDUS the default.

It also incorporates an updated fix for compilers that don't support ULL constants. The expression in question was already guint64 so the constants don't need to be.
