First I want to thank everyone for your help. Second, i want to share an idea: What about writing a "driver" that allows the kernel to see both eth cards as one, and its job is to test the cards failure etc... this driver is compiled as a module for virtual eth0 which in fact is based on 2 physical cards. Do you think what i'm saying here makes sense? Did someone hear of a similar project I can take some ideas from, to put me on the right track?
