-The "classify filter" debug CLI command constructs an arbitrary set of
- packet classifier tables for use with "pcap rx | tx trace," and
- (eventually) with the vpp packet tracer

Packets which match a rule in the classifier table chain will be
traced. The tables are automatically ordered so that matches in the
