 It most certainly does not.  People have been using an MTU/MRU of >1024
 about forever.  For example I've been rp-pppoe for some 10 years with
 and MTU of 1492.  That runs pppd on a pty to give it a tty interface.
 
 Maybe if you could state the actual problem a solution could be arrived
 at instead of through random patches around.
