sys/netinet/in_pcb.c
1187	It looks like we can use `sin' that is already initialized.
sys/netinet/ip_icmp.c
972	In another review you told that proper sin_family initialization is not required. Will sa_equal work correctly in this case? Is this structure properly initialized? :)
sys/netinet6/ip6_fastfwd.c
284	Does sin6_addr here have embedded scope zone id? LLE lookup did need address with embedded scope zone id. Did you make test when GW address is LLA?

sys/netinet/in_pcb.c
1187	Good catch! Will update the review shortly.
sys/netinet/ip_icmp.c
972	sin_family initialisation is not required for the lookup. Gateway sockaddr in the nexthop is aways filled in properly. As here `src` should also be proper sockaddr, I guess it should continue working as is.

sys/netinet6/ip6_fastfwd.c
284	Yes, the gateway always have scopeid embedded - exactly for the purpose of passing it to LLE. At some point in time we should just convert LLE layer to accept non-embedded addresses and mark l3+l2 lookups as embed-free
