I took two devices and equipped them with USB WLAN cards: Bus 001
Device 003: ID 148f:5370 Ralink Technology, Corp. RT5370 Wireless
Adapter. One device as AP and another as client. Client makes
permanent ping to AP. And from time to time I start nuttcp session.
After 2-3 days I get following errors:
2-3 days ? oh man... :-)
Here's one thing to try. Can you do some variable size pingtest ?
Something like below should do ?
random()
{
size=$(dd if=/dev/urandom count=1 2/dev/null|cksum|
cut -f1 -d |tr '-' '\0')
size=$(expr $size % 6)
}
num=$1
if [ -z $num ]
then
num=1

while ! ifconfig usb0 /dev/null 21; do
printf waiting for usb0\n
sleep 1;
done
ifconfig usb0 192.168.2.14
for i in $(seq 1 $num); do
random
printf %d: \t pinging with size %-27d $i $size

Still haven't tried your test, but have seen this interesting
patch/proposal http://e2e.ti.com/support/arm/sitara_arm/f/791/t/404743.
Seems to be somehow related.
patch makes sense. If you can make sure it really solves your problem
then send it as a proper patch on top of my testing/next, I'd be glad.
FYI, the patch is posted here
http://marc.info/?l=linux-usbm=142526223500889w=2.
At some point, I'll just split dma callback into dedicated rx and tx
callbacks to avoid confusion in the future.
