misc: classifier-based packet trace filter
See .../src/vnet/classify/trace_classify.h for the business end
of the scheme.
It would be best to hash pkts, prefetch buckets, and do the primary
table lookups two at a time. The inline as given works, but perf
tuning will be required. "At least it works..."
Add "classify filter" debug cli, for example:
classify filter mask l3 ip4 src dst \
match l3 ip4 dst 192.168.2.10 src 192.168.1.10
Add "pcap rx | tx trace ... filter" to use the current classify filter chain
Patch includes sphinx documentation and doxygen tags.
Next step: device-driver integration
Type: feature
