<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi,<br>
I have a doubt about the problem that fq_codel has with 802.11n packet aggregation, and your help to understand the problem would be well accepted.<br>
<br>
Could you explain me how and in which real terms (for example, through an example) ath9k underlaying queue will limit fq_codel effect?<br>
I imagine that ath9k will only add some delay that can't be controlled by fq_codel, but I can't imagine how delay could grow in case of fillfullment of ath9k's queue...<br>
<br>
Also, I read that fq_codel drops packets at head of queue. So, if fq_codel can't manage and act over ath9k queue, will fq_codel's effect change and not to work as expected? I'm thinking, for example, at the most common TCP congestion control techniques: will
TCP be able to correctly understand what fq_codel wanted to announce, if it isn't droping packets at the very first level of queuing?<br>
<br>
Thanks<br>
