/* * Set connection variables based on the peer's advertised MSS. * We are passed the TCPCB for the actual connection. If we * are the server, we are called by the compressed state engine * when the 3-way handshake is complete. If we are the client, * we are called when we receive the SYN,ACK from the server. * * NOTE: Our advertised MSS value must be initialized in the TCPCB * before this routine is called! */
