[PATCH 2/2] net/ipv6: Fix misuse of proc_dointvec "skip_notify_on_dev_down"

From: Eiichi Tsukata
Date: Mon Jun 24 2019 - 23:08:30 EST


/proc/sys/net/ipv6/route/skip_notify_on_dev_down assumes given value to be
0 or 1. Use proc_dointvec_minmax instead of proc_dointvec.

Fixes: 7c6bb7d2faaf ("net/ipv6: Add knob to skip DELROUTE message ondevice down")
