AR8334 identifies itself as AR8337/rev.2. There might be a real AR8337/rev.2 with 7 ports. How to tell between these two chips? 2. The AR8334 name seems to indicate that it's the same as AR8337 just with 4 ports. The required padding patch however shows that the difference is not only the number of ports. Having said that there might be more differences.
