[lwip-users] TCP retransmission

[Nikolas Karakotas]

Hi,

I'm facing an issue on-site where there is quite a lot of traffic.
Sometimes I can see from the log that we have a TCP re-transmission
and we once the packet is re transmitted the data we receive is
impartial. As a result our modbus driver responds with and error.
I can see that the the modbus header is partial correct but the rest
is junk. This is very difficult to reproduce but some insight may help
me to find the issue. So do you believe it's an issue with the:
1. Ethernet driver
2. Application layer dealing with fragmented packet
