Subject: [PATCH net-next 0/8] ipv6: icmp6: better drop reason support

This series aims to have more precise drop reason reports for icmp6.

This should reduce false positives on most usual cases.

This can be extended as needed later.

Eric Dumazet (8):
  ipv6: icmp6: add drop reason support to ndisc_recv_ns()
  ipv6: icmp6: add drop reason support to ndisc_recv_na()
  ipv6: icmp6: add drop reason support to ndisc_recv_rs()
  ipv6: icmp6: add drop reason support to ndisc_router_discovery()
  ipv6: icmp6: add drop reason support to ndisc_redirect_rcv()
  ipv6: icmp6: add SKB_DROP_REASON_IPV6_NDISC_BAD_OPTIONS
  ipv6: icmp6: add SKB_DROP_REASON_IPV6_NDISC_NS_OTHERHOST
  ipv6: icmp6: add drop reason support to icmpv6_echo_reply()
