[lwip-users] RE:RE:RE Losing packets.

Losing packets:

It seems that there is a real problem here. I am happy to try and
implement a solution since it effects my current project.

I have some questions to ask first:

Can someone explain the idea behind etharp queuing? Why has it been
added and which RFC is it implementing?

If there is a block on the output of the stack, would it make sense to
block the input directly (ie a new flag)? ie, when blocked, tcp_write()
writes 0 bytes. OR, will the internals of the stack manage this?

I would expect the queue to stack a number of packets ( in order ). I
would like to use the 'transmitter free' interrupt on my ethernet driver
to output these packets. Is this a good idea or would a retry timer,
possibly the tcp timer be a safer way to do it?

Any other comments, or places to look for information would be
appreciated.

Chris.
