Correct the MTU for 7.2 config files

Browse Source 
Even though the jumbo frame has 9600 bytes by the spec, the max MTU is limited to the MTU of a switch, if any used.
However, the value can be < max MTU of a switch.

This is very important for fragmentation purposes. If not properly set, the PDSCH packets will be missing.
