In tcp_write() function, why we don't allocate segments bigger than half the maximum window we ever received?Is this a LwIP requirement or TCP protocol requirement?
This is to achieve decent throughput with remote hosts implementing delayed ack. Without having 2 or more segments in flight, they would wait ~250ms for each ack and connection speed would be very low.
