MFC r310258:
  ip[6]_tryforward does inbound and outbound packet firewall processing.
  This can lead to change of mbuf pointer (packet filter could do m_pullup(),
  NAT, etc). Also in case of change of destination address, tryforward can
  decide that packet should be handled by local system. In this case modified
  mbuf can be returned to the ip[6]_input(). To handle this correctly, check
  M_FASTFWD_OURS flag after return from ip[6]_tryforward. And if it is present,
  update variables that depend from mbuf pointer and skip another inbound
  firewall processing.
