eBPF Implementation for FreeBSD

This project proposes eBPF implementation for FreeBSD. It will have very basic functionality such as maps, interpreter, JIT compiler for x86-64 and character device + ioctl interface which is an alternative of Linux bpf(2). To introduce how it is useful, we will implement eBPF extension module for VALE software switch which can be used to write very fast middle box (firewall, load balancer and so on) easily.
