    samples/bpf: add comprehensive ipip, ipip6, ip6ip6 test · 173ca26e

    the test creates 3 namespaces with veth connected via bridge.
    First two namespaces simulate two different hosts with the same
    IPv4 and IPv6 addresses configured on the tunnel interface and they
    communicate with outside world via standard tunnels.
    Third namespace creates collect_md tunnel that is driven by BPF
    program which selects different remote host (either first or
    second namespace) based on tcp dest port number while tcp dst
    ip is the same.
    This scenario is rough approximation of load balancer use case.
    The tests check both traditional tunnel configuration and collect_md mode.
