In my case, I'm only trying the latest firmware to test all possibilities
before asking the list of my __real__ prism2 problem.
Currently, with secondary 0.8.0 firmware (the most recent that compaq
provides), I'm getting a massive amount of INFDROP events, under very high
load conditions that I test IP DiffServ Quality of Service Traffic Control
in 802.11 Downstream. (this traffic is generated in UDP, creating much more
traffic than a flood ping).
Also, related to this problem, when these continous INFDROP events happen, I can't get new stations associated to the AP, as the ASSOC frame doesn't seem to get transmitted. This causes the station to send ASSOC frame every X seconds in a loop. Unfortunatelly, I also need Associations under these very high loads, to test both 802.11 handover and IP level handover (check http://wuarchive.wustl.edu/doc/internet-drafts/draft-estrela-timip-00.txt.Z or http://tenet.knu.ac.kr/research/seminar/jwkim_020712.ppt)
However, i'm trying the latest firmwares for my old PCMCIA cards, to check if the situation improves before i try to rate-limit/packet-limit transmissions in the driver.
