All the VIA Rhine Fast Ethernet controllers follows the IEEE standard (inter-frame gap is 96 bit time) and it is hardware fixed and NOT programmable. > "Can misprogramming the chip lead to the effect that the inter-packet > gap is never less than 112 bit times?" => NO, it is fixed and neither software nor board level change could modify the inter-frame gap of VIA Rhine Fast Ethernet controller. > > Of course, you can always check if VIA's driver has the same issue.

Where can I find it? => in http://www.viaarena.com/ , choose "downloads" => "Drivers" => choose target OS (e.g. Fedora Core Linux) => "Ethernet (Networking/LAN)" => choose the type of your Ethernet controller => click to download the combo driver software package.
