## Summary If we only enable one of `CONFIG_NET_ARP_SEND` and `CONFIG_NET_ICMPv6_NEIGHBOR`, both IPv4 and IPv6 traffic will send ARP or NDP, which causes problem. Example: `CONFIG_NET_ARP_SEND=n` `CONFIG_NET_ICMPv6_NEIGHBOR=y` Wrong: IPv4 traffic (`PF_INET`) goes into `icmpv6_neighbor`, which definitely causes problem. Correct: IPv4 traffic doesn't call anything, IPv6 traffic calls `icmpv6_neighbor` ## Impact The behavior of `CONFIG_NET_ARP_SEND` and `CONFIG_NET_ICMPv6_NEIGHBOR`, especially when we only enable one of them. ## Testing Manually & CI -- This is an automated message from the Apache Git Service.
