Well, the intial values are more or less hardwired in. See:

	freebsd/3.x/src/sys/netinet/udp_usrreq.c
	freebsd/3.x/src/sys/netinet/tcp_usrreq.c

Look for sendspace and recvspace. However, the connection setup can modify
those values, although I'm not clear on details of it. Have a peek and let
us know what you discover.
