I was working on some driver and while I was setting up the interrupt stuff, I set up a wrong Interrupt Level, which, I guess, was being used by the ethernet driver . This messed up the ethernet driver and so the problems. I apologize to everyone for this. I appreciate all the answers. I am totally new at writing drivers and hence, the hiccups.
