The NuttX port of uIP imcludes logic to send data ahead without - waiting for ACKs from the recipient; this greatly improves throughput. - However, the packet sequence number was not being updated correctly and, - as a result, packets were not be ACKed by the recipient and transfers - would sometimes stall.
