Below is a perplexing problem that I am hoping the LARTC kernel experts can help me with. We have a traffic control system based upon htb which when packets are directed to it from a bridge between eth2 and eth3 works great. Accurate adherence to specified link rates based upon priority is achieved. For example, if I have a 2 Mbps UDP stream going to Q-PRI4 and another 2 Mbps UDP stream going to Q-PRI5 with a link rate of 800Kbps, then 800K of traffic is sent from Q-PRI4 with and the rest of the packets on Q-PRI4 are dropped, and 100% of the packets directed to Q-PRI5 are dropped. This is exactly how it should work. BUT using all the same traffic control rules, if we intercept packets on eht2 with PF-RING and then output to eth3 with raw socket packet sends , the QDisc does not work the same. Instead Q-PRI4 and Q-PRI both get 400K of traffic. The higher priority of Q-PRI4 is not respected. Why does it behave differently when intercepting packets from PF-RING and then doing raw sends versus how it works with a classic bridge ? Another observation is that if I have a queue limit of 45 or less. Then it works correctly in both scenarios. But if I have a queue limit higher than 45 then it disregards the priority of the Q. -- To unsubscribe from this list: send the line "unsubscribe lartc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
