MFC r328541:
Do not skip scope zone violation check, when mbuf has M_FASTFWD_OURS flag. When mbuf has M_FASTFWD_OURS flag, this means that a destination address is our local, but we still need to pass scope zone violation check, because protocol level expects that IPv6 link-local addresses have embedded scope zone indexes. This should fix the problem, when ipfw is used to forward packets to local address and source address of a packet is IPv6 LLA. Reported by: asomers@
