From 4f5f85e9a70e13c8919e26609914253d18fbf858 Mon Sep 17 00:00:00 2001 From: Guillaume Nault Date: Fri, 10 Aug 2018 13:22:03 +0200 Subject: l2tp: let pppol2tp_ioctl() fallback to dev_ioctl() Return -ENOIOCTLCMD for unknown ioctl commands. This lets dev_ioctl() handle generic socket ioctls like SIOCGIFNAME or SIOCGIFINDEX. PF_PPPOX/PX_PROTO_OL2TP was one of the few socket types not honouring this mechanism.
