act_bpf: add initial eBPF support for actions
This work extends the "classic" BPF programmable tc action by extending its scope also to native eBPF code! Together with commit e2e9b6541dd4 ("cls_bpf: add initial eBPF support for programmable classifiers") this adds the facility to implement fully flexible classifier and actions for tc that can be implemented in a C subset in user space, "safely" loaded into the kernel, and being run in native speed when JITed. Also, since eBPF maps can be shared between eBPF programs, it offers the possibility that cls_bpf and act_bpf can share data 1) between themselves and 2) between user space applications. That means that, f.e. customized runtime statistics can be collected in user space, but also more importantly classifier and action behaviour could be altered based on map input from the user space application. For the remaining details on the workflow and integration, see the cls_bpf commit e2e9b6541dd4. Preliminary iproute2 part can be found under [1].
