From 54fecff3461143bfc4c4f0431e9145e8748977ce Mon Sep 17 00:00:00 2001 From: Doug Berger Date: Mon, 13 Mar 2017 17:41:39 -0700 Subject: [PATCH] net: bcmgenet: return EOPNOTSUPP for unknown ioctl commands This commit changes the ioctl handling behavior to return the EOPNOTSUPP error code instead of the EINVAL error code when an unknown ioctl command value is detected. It also removes some redundant parsing of the ioctl command value and allows the SIOCSHWTSTAMP value to be handled. Signed-off-by: Doug Berger Reviewed-by: Florian Fainelli Signed-off-by: David S.
