Until you actually make a connection the kernel has no idea what the MSS and thus twice MSS values for a connection could be. The device MTU can also shift if routes shift. It would be nice for the kernel to veto your settings. The only easy way to do this I can see is to simply refuse to drop the RCVBUF below 16K (twice the FDDI mtu).
