Maximum Transmission Unit (MTU) the size (in bytes) of the largest packet or frame that a given layer of a communications protocol can pass onwards. The MTU may be fixed by standards (as is the case with Ethernet) or decided at connect time. A higher MTU brings higher bandwidth efficiency. However, large packets can block up a slow interface for some time, increasing the lag for further packets.

In openSUSE 11.0, the network setup is by default controller by “NetworkManager” and this is different from the traditional netcontrol. With NetworkManager, users control the Network Interfaces. To confirm this, in GNOME from Computer - Yast - Network Devices - Network Settings, check for option “User Controlled with Network Manager” under Network Setup Method. Or, check for the line ‘NETWORKMANAGER=”yes”‘ in /etc/sysconfig/network/config file.
This may not be a viable option to use on SUSE enterprise Desktop as in a enterprise environment you wouldn’t want the user to modify or control network settings.
