Hey Guys,

One of my first non-trivial contributions to mesa here. Let me know if I've messed up anything, bad coding style or some patch validation script I should've run or any other kind of pitfall a newbie might make.

I tried to follow the guidelines over at:

Although some of them seen to not apply anymore (radv code was tabs instead of 3 spaces).

Thanks for taking the time to review :)
