tc Trafic shapping help requested

[Bryan O'Neal]

You can filter by port with the option like "sport 80" but so far I have
not found a way to say "not port 80" ingress traffic I know ingress shaping
is not as robust but I thought you could put policies around it.

Still learning this stuff - I will chat with Gorz today :)
