ipv6: flush nd cache on IFF_NOARP change
This patch is the IPv6 equivalent of commit
6c8b4e3ff81b ("arp: flush arp cache on IFF_NOARP change")
Without it, we keep buggy neighbours in the cache, with destination
MAC address equal to our own MAC address.
Tested:
tcpdump -i eth0 -s 0 ip6 -n -e &
ip link set dev eth0 arp off
ping6 remote // sends buggy frames
ip link set dev eth0 arp on
ping6 remote // should work once kernel is patched
