From acd1130e8793fb150fb522da8ec51675839eb4b1 Mon Sep 17 00:00:00 2001 From: Michał Mirosław Date: Mon, 24 Jan 2011 15:45:15 -0800 Subject: net: reduce and unify printk level in netdev_fix_features() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Reduce printk() levels to KERN_INFO in netdev_fix_features() as this will be used by ethtool and might spam dmesg unnecessarily. This converts the function to use netdev_info() instead of plain printk(). As a side effect, bonding and bridge devices will now log dropped features on every slave device change.
