This warning message was removed in change 
083a5f00a15f6506815b0da2be82e7be761c5cbc
In this patch is checked, whether warning should be printed. Output
of "tc filter <type> help" isn't spoiled after my change.

Actually, protocol is not required. It defaults to all.
But I did go ahead and make help just return.
