From 342a437ef625953e8bdeee3bc1605ccd27a38863 Mon Sep 17 00:00:00 2001 From: André Goddard Rosa Date: Fri, 29 May 2009 22:13:58 -0700 Subject: usbnet: ratelimit warning messages invoked from callback handler MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Warning messages coming from rtl8150 driver can flood the console and make a DTV/set-top-box unable to decode video/audio frames. 'Pegasus' driver handles this situation similarly, preventing this from happening there. It happens with a low cost BCM MIPS embedded platform, whenever timeout errors were coming from usbnet device, making platform unusable for viewer watching.
