net/ipv6: Fix misuse of proc_dointvec "skip_notify_on_dev_down"
Browse files Browse the repository at this point in the history
/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: 7c6bb7d ("net/ipv6: Add knob to skip DELROUTE message ondevice down")
