From aa435eec4cfd1794438ea8593fff0181c70dcebf Mon Sep 17 00:00:00 2001 From: Daniel Borkmann Date: Sat, 13 Jul 2013 15:01:39 +0200 Subject: ifpps: warn when 1Gbit/s and interval < 1sec It is possible to use a interval even of 0, although it would not really make sense. It's not a bug either, so throw a warning to the user in that case on 1Gbit/s.
