I think only one question came up for me during it, which is support for a bfifo and pfifo qdisc? (if I missed something let me know ) Support for these are darn useful for the research and I have long meant to fold in the modified code I use for that. Byte limits are very common for cable and dsl technologies and doing tests with 64k,128k,256k, and 512k bfifos is quite revealing. (I have a ton of plots lying about for this, I should put them up somewhere) Sooo... I just checked in the limit stuff (untested) into aqm-scripts. It requires that the limit option be dynamic and exposed to the gui, and in the case of a bfifo is a byte limit rather than a packet limit. There needs to be sane values for limit clamped somehow, as 1000 bytes would be bad, and 512000 packets would be bad also. As for folding the selection of bfifo or pfifo into the gui, it's not clear that we are doing "researcher mode", vs "mom mode" in a suitably abstract way. Certainly I can imagine many a researcher wanting the gui. While I'm at it, there are some statistics like drops, and backlog, etc, that a gui-ish interface might help. polling tc -s qdisc show dev ge00 # and/or class show dev ge00 I am curious if anyone is seeing the DMA tx error in 3.10.24-5? I have one box that has now been up 4.4 days with no errors, but I haven't pushed it. I'll be beating it up through the weekend and taking a look at the gui work so far.
