Revert "return the correct address family?"
...
not really needed....looks safe so long as the bytes are in network order (hence, the inet4 link will only grab the top 32 bits of the whole inet6 address field.)
This reverts commit 56e41ebda0c29bb2a85dd3f8dbbfba30da8c0a2c.

ip: code cleanups and compatibility improvements
...
do not assume that packets come with address zero-ed, older clients don't do that.
they don't modify checksum either, therefore we should be able to get correct checksum if we use deltachksum with old and new addresses.

correct dst address is required for FlushSend to work, so do IP address and checksum null'ing there.

clearing of addresses and checksum was put in wrong place, so it null'd everything before writing to tun interface.
