Let's see > what we can come up with. First of really thanks for your valuable review. It may seem to be illogical to have two separate drivers, however as explained in past we are working on another solution for some upcoming thing. In that case we need MP2-PCI communication driver which will be reused. At this point of time i can't talk much about that but once solution is ready, we will be pushing that as well. Hence i sincerely requesting to have two separate driver. For rest of remaining comments will look into the same. Elie hope you will also have a look and we will have a common understanding. > Thanks, > > Wolfram > Thanks for consideration and your understanding. Regards Nehal Shah
