In the patch 3, you rename this flags. It would be easier to understand if
the right names were used in the first patch.

When renaming ETH_SPEED_CAP, this line is not changed later.

This is made in purpose.
In patch 3/5 the bitmap speeds are renamed to ETH_LINK_SPEED_XXX and
numeric values are moved ETH_SPEED_NUM_XXX, to make clear the difference. I
cannot, in this commit, rename them directly to ETH_LINK_SPEED_XXX since
they would collide with the current numeric speeds.
Thanks
Marc
