Is there any easy way to change the MTU and the TCP MSS?  I'm 
(temporarily) stuck behind a broken gateway that is dropping "large" 
packets, so I want to crank down the TCP MSS.  I can change the 
interface mtu via ifconfig, but that doesn't seem to change TCP's idea 
of how large a segment it wants.
