BPF is used quite intensively inside Linux (and BSD) kernels for various different purposes and proved to be extremely useful. BPF inside DPDK might also be used in a lot of places for a lot of similar things. As an example to: - packet filtering/tracing (aka tcpdump) - packet classification - statistics collection - HW/PMD live-system debugging/prototyping - trace HW descriptors, internal PMD SW state, etc. The presentation provides information about current status of DPDK eBPF library and ideas for further enhancements and usage scenarios.
