> Just wanted to know if IFG is configurable programatically. There is a small chance that some model of ethernet card makes the IFG programmable, but I've never seen a device driver making that configurable, and there is no logic in the kernel to ask a driver to do so. You would have to ask a card manufacturer for the exact programming sequence, then adapt the driver to initialize it accordingly, and if you want to make it settable from userspace, you have to invent a new downcall in the device driver API, along with a new socket option for the user to call down there. > I am trying to send too many UDP Packets and so am having packet loss.

How would loss be reduced by _reducing_ the number of packets you _can_ send? The packets are probably dropped right inside the sending machine's kernel, due to a filled output queue. That's fine, UDP is lossy. Don't send so many packets, if that is bad for you. Forget the IFG.
