[lwip-users] Losing packets

[Chris WIlliams]

I am losing packets when transmitting:

I am sending packets to my ethernet interface using the
low_level_output() routine in ethenetif.c. I am sending the data very
quickly, and at some point I fill up the buffer in the ethernet chip and
I can't store any more data. I therefore drop the packet, and return
ERR_IF.

I assumed that at this point the TCP/IP would stop, and retry again in
the future. However, the returned value from low_level_output() is never
examined and the packet is lost. The next packet is transmitted OK, and
then it takes time for the system to recover.

Does anybody have an comments or a fix for this?

Thanks for your help.

Chris.
