IMO, calling it BPF_F_EGRESS would be less confusing. It's a shame we
can't have the same flag API between bpf_redirect() and
bpf_redirect_peer(), but this is creating inconsistent semantics for
the terms egress/ingress across the two helpers.

Yeah, one annoying thing about BPF_F_EGRESS is that it would only
apply to bpf_redirect_peer, so you still have inconsistencies across
helpers. Perhaps this is less weird than having BPF_F_INGRESS perform
an egress redirection though.
