hi kieran,
lwip is sending the packets. you say that it can be a recource
allocation problem .. how can i ensure that lwip gets what it wants! i
mean i always check lwip.stats but is there a way to check if lwip waits
for an sem to get signaled or so?
i'll post a trace and my opts.h tomorrow since i don't have them on this
machine.
