Subject: kni: return failure for all ioctls
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=12ce2da88f032efb7bf2e3ed4e1037f220869251;p=dpdk.git

kni: return failure for all ioctls

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.
