[PATCH iproute2 master] {f,m}_bpf: dump tag over insns
From: Daniel Borkmann <daniel@iogearbox.net>
Date: 2017-02-23 12:07:22
We already export TCA_BPF_TAG resp. TCA_ACT_BPF_TAG from kernel commit
f1f7714ea51c ("bpf: rework prog_digest into prog_tag"), thus also dump
it when filter/actions are shown.
