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 Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I05b1358a769f61e6d32470e0c87058f640486b26
