 => YES. 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.

 => NO, it is fixed and neither software nor board level change could
modify the inter-frame gap of VIA Rhine Fast Ethernet controller.

 => 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.
