[Q] TCP segment sent is larger than peers advertised MSS

Hello,

I am in the process of troubleshooting another problem and noticed a rather strange behavior with the openssh client. A client (OpenSSH 5.3) and a server (6.7p1) do the TCP handshake, the client announces a MSS of 1460 (its MTU is 1500), while the server announces a MSS of 1260 (its MTU is set to 1300). What troubles me is, that the client is sending the server a frame of 2034 bytes (TCP segment length of 1968, during the "Client: Key Exchange Init"). Why is it that the client seems to ignore the servers MSS?

Thanks for your input
