The two aren't related. The SO_xxxBUF parameters define the the size of a send/receive buffer associated with a specific socket in order to prevent network applications from using all available memory. For high-volume applications you would typically set a larger value, up to the maximum size allowed. The TCP send/receive buffers are not affected by the socket buffer sizes. TCP buffers are dependent on the maximum segment size (MSS). It is the MSS that is dependent on the MTU, being chosen to avoid fragmentation.
