Ah, that does indeed put another light on dissecting, filtering and
coloring sFlow. I expected it to have only one header in it's payload :-)

Are you able to share a small capture file with some sFlow packets
with multiple headers as payload? I'm interested to have a look at
it to see what I would find useful...
