In searching around the web I have found information on how to prioritize traffic with Open BSD but not with Linux. Specifically I am looking to prioritize TCP ACKs. This will help downloads when someone uploads on a broadband connection so that the download speed is not killed. Now, the information I have seen is using ALTQ and pf.conf with Open BSD. Is there an equivalent to this in Linux? I have looked at Netfilter but I have not seen anything that specifically relates to this.
