librte_bpf provides a framework to load and execute eBPF bytecode inside user-space dpdk based applications. It supports basic set of features from eBPF spec (https://www.kernel.org/doc/Documentation/networking/filter.txt). Not currently supported features: - JIT - cBPF - tail-pointer call - eBPF MAP - skb - function calls for 32-bit apps - mbuf pointer as input parameter for 32-bit apps Signed-off-by: Konstantin Ananyev <konstantin.ananyev@intel.com> Acked-by: Ferruh Yigit <ferruh.yigit@intel.com>
