Subject: Ethtool question

I noticed today that setting some ethtool settings to the same value
returns an error code.  I would think this should silently return
success instead?  Makes it easier to call it from scripts this way:

[root@...313-6477 lanforge]# ethtool -L eth3 combined 1
combined unmodified, ignoring
no channel parameters changed, aborting
current values: tx 0 rx 0 other 1 combined 1
[root@...313-6477 lanforge]# echo $?
1

Thanks,
Ben
