due to massive changes in KAME side. - IPv6 output goes through nd6_output - faith can capture IPv4 packets as well - you can run IPv4-to-IPv6 translator using heavily modified DNS servers - per-interface statistics (required for IPv6 MIB) - interface autoconfig is revisited - udp input handling has a big change for mapped address support. - introduce in4_cksum() for non-overwriting checksumming - introduce m_pulldown() - neighbor discovery cleanups/improvements - netinet/in.h strictly conforms to RFC2553 (no extra defs visible to userland) - IFA_STATS is fixed a bit (not tested) - and more more more. TODO: - cleanup os-independency #ifdef - avoid rcvif dual use (for IPsec) to help ifdetach (sorry for jumbo commit, I can't separate this any more...)
