This patch should go away. With patch 2 user can chose the right
coalescing settings for themselves. adaptive coalescing means that 
the driver adjusts the coalescing settings based on _traffic_ not
link speed. Please don't (ab)use that for the trivial link speed based
heuristic. There's a library called DIM which implements the dynamic
algo which you can plug into your driver if you want (it even has docs)
