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.
