That should probably be _ratelimited, but it seems we don't have
_ratelimited variants for the netdev_* helpers.

Right.
I have used the net_*_ratelimited() variants when needed.
Too bad we don't have those.

If you think netdev_dbg_ratelimited() would be useful, i don't see why
you cannot add it.

I just did an search and found something interesting in the history:

Maybe limit it to netdev_dbg_ratelimited() to avoid the potential
abuse DaveM was worried about.
