Much ado about very little in this thread. The subject of running eBPF in VPP goes back to at least May 2016.
I don't know of any current plans to support running eBPF or P4 in VPP. There was a short-lived project to run eBPF VPP as a trace engine: https://gerrit.fd.io/r/q/ebpf and a different project to run P4 in VPP: https://gerrit.fd.io/r/admin/repos/p4vpp neither resulted in much interest, and with good reason. It's likely just as easy (and more performant) to write a (set of) VPP node(s). There is an AF_XDP driver for VPP at src/plugins/af_xdp and you can use a custom eBPF program against the underlying kernel interface. This may be enough for your needs, or it may not.
