2019-09-20misc: classifier-based packet trace filterDave Barach1-0/+108
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

2018-11-13vlib rename vlib_frame_args(...) to vlib_frame_scalar_args(..)Damjan Marion1-1/+1
Typically we have scalar_size == 0, so it doesn't matter but vlib_frame_args was providing pointer to scalar frame data, not vector data. To avoid future confusion function is renamed to vlib_frame_scalar_args(...) Change-Id: I48b75523b46d487feea24f3f3cb10c528dde516f Signed-off-by: Damjan Marion <damarion@cisco.com>
