I recently wrote a howto here, but there's also excellent documentation
in terms of man pages for bpftool.

http://cilium.readthedocs.io/en/latest/bpf/#bpftool

My original thinking was that it might be okay to also show usage of
short option matching, like in iproute2 probably few people only write
'ip address' but majority uses 'ip a' instead. But I'm fine either way
if there are strong opinions ... thanks Alexei for fixing up!
