I'd advice you to seriously look over your network, are you 100% sure you don't have a duplex-issue anywhere?
I've been running linuxrouters for quite a while and right now I have a few linuxrouters routing 100Mbit/s internetconnections. We have never had any problems like the one you describe so my first guess would be that you have a duplexproblem, probably between the linuxrouter and the switch it's connected to on the inside, that's usually where it's located. Or maybe between some switches or something but do look into this. I seriously doubt that this a problem with the networking in linux.

Never argue with an idiot. They drag you down to their level, then beat you with experience.
