#define TCP_MSS

Default maximum segment size.
The maximum size of an IP datagram, that will not become fragmented, is 576. The maximum IP datagram for Ethernet is 1500. Reduce this number by 40, 20 bytes TCP header and 20 bytes IP header.

#define TCP_WINSIZE

Default window size.
It's recommended to set this 6 times the maximum segment size.
