[Ethernet Frame Size Set-up]
Configure ethernet frame size. If frame size is unknown, set it to 1500.
* Ethernet Frame Size: If the Ethernet frame size is at least 1500 gigabits, specified
files can be sent quickly and with ease. In this case, the LG Network Storage
alone does not change, but so do the PC and home router/router/hub/switch
frame sizes. Otherwise performance will be reduced.
