-# This test sets up 3 netns (src <-> fwd <-> dst). There is no direct veth link
-# between src and dst. The netns fwd has veth links to each src and dst. The
-# client is in src and server in dst. The test installs a TC BPF program to each
-# host facing veth in fwd which calls into i) bpf_redirect_neigh() to perform the
-# neigh addr population and redirect or ii) bpf_redirect_peer() for namespace
-# switch from ingress side; it also installs a checker prog on the egress side
-# to drop unexpected traffic.
