[dpdk-dev] [PATCH] kni: return failure for all ioctls

[Dan Gora]

Modify kni_net_ioctl() to return -EOPNOTSUPP for all ioctls instead
of 0.

This is necessary because the Wicked (and possibly other) network
interface managers will perform the SIOCGIWNAME ioctl to check if
the interface is a wireless interface.  If the KNI module returns
success, Wicked will incorrectly interpret the interface as a wireless
interface.
