it sounds like something in the logic is suspending the ru too much, but
I haven't had time to look deeply into the code yet.
I don't have an e100 enabled x86 box handy but I will look into getting one
setup.
I just applied this patch to my PXA255 based system
http://www.compulab.co.il/x255/html/x255-cm-datasheet.htm .
It is running 2.6.18.4 plus compulab patches plus some hostap patches plus the
e100 patch. I get:
pings going from the embedded system to a desktop machine.
100 packets transmitted, 100 received, 0% packet loss, time 98996ms
rtt min/avg/max/mdev = 0.239/0.728/1.512/0.571 ms
Pings going the from the desktop machine to the embedded system
100 packets transmitted, 100 received, 0% packet loss, time 99217ms
rtt min/avg/max/mdev = 0.206/0.876/1.473/0.575 ms
ok, I just got a note from our lab saying that that particular system has the
freak ping times even without your patch applied 8)
ignoring the ping issue, we still have the ru offline, but that could have
possibly been caused by whatever is causing this ping issue... More testing is
needed, and I'll try to find a system without the ping issue here first.
