[pcap-ng-format] IDB: "description" vs. "friendly name"

[Jasper Bongertz]

Yeah, that's something I stumbled across a while ago, too. Two options
are a good idea. We need to add an example to the spec to show what we
mean by either one. I can't really decide between "if_friendly_name"
and "if_descriptive_name", but I'd probably vote for
"if_descriptive_name".

Cheers,
Jasper
