Plan was to follow up patch will rename enum tc_setup_type too:

https://marc.info/?l=linux-netdev&m=153193158512556&w=2

that will result in more renames in the driver side.

I would expect this will happen sooner or later, and out of tree
patches will end up needing a rebase sooner or later, if that is the
concern.
