Vinicius Costa Gomes b5b73b26b3 taprio: Fix allowing too small intervals ... It's possible that the user specifies an interval that couldn't allow any packet to be transmitted. This also avoids the issue of the hrtimer handler starving the other threads because it's running too often. The solution is to reject interval sizes that according to the current link speed wouldn't allow any packet to be transmitted.
