Almost missed this.
Any reason you're adding to the uAPI header?
Just because that's where SPEED_UNKNOWN is defined?
IIRC lanes are only reported via netlink, so we don't need
to worry about sharing unspecified values with user space.
Stuff added to the uAPI header is harder to clean up,
if you don't have a strong reason I think we should move
these defines to the kernel header.
