From 038890fed8d1fa95bbbdeb517f5710eb75fa9e2e Mon Sep 17 00:00:00 2001 From: Thomas Graf Date: Thu, 5 Apr 2007 14:35:52 -0700 Subject: [PATCH] [RTNL]: Improve error codes for unsupported operations The most common trigger of these errors is that the config option hasn't been enable wich would make the functionality available. Therefore returning EOPNOTSUPP gives a better idea on what is going wrong. Signed-off-by: Thomas Graf Signed-off-by: David S.
