I have now tested both contribs on 6.01 and they seems to work. But they don't do deliver what I consider Quality Of Service. The eneo contrib makes sure that all lan nic's gets the same bandwith, which is sort of QoS. The sme-QoS makes sure that some ports are prioritiesed lover than the rest. But you don't get the chance to give som ports a higher priority.
I am sure, that the system behind the two contribs are cable of doing more complex things. Is there anyone who can confirm that?
