I want top half of tx interrupt to be in User space . I want to implement some alogoritm in userspace to drop packets on high flooding and to keep other processes's some cycles . Could you guide me a little on this , any online turorials or articles or books , i can refer ? Any similar implementation like this ? Thanks, Ratheesh.
