Subject: [PATCH] IPROUTE: tc correct error message

From: Marcela Maslanova <[email-masked]>
Date: Mon, 22 Sep 2008 15:52:36 +0200

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.
