From c34b8bb11ebc135e970653bd6fc8e3f863fb6a81 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Thu, 16 Feb 2023 16:28:41 +0000 Subject: ipv6: icmp6: add SKB_DROP_REASON_IPV6_NDISC_NS_OTHERHOST Hosts can often receive neighbour discovery messages that are not for them. Use a dedicated drop reason to make clear the packet is dropped for this normal case. Signed-off-by: Eric Dumazet Signed-off-by: David S.
