ADDED: * netx now has a ton of netmask conversion functions for IPv4 netmasks. (IPv6 doesn't really *have* netmasks, so it was intentionally excluded).
FIXED: * Missed a Reset on the inetcksum.InetChecksumSimple.
FIXED: * Windows logging ADDED: * netx (and netx/inetcksum), the latter of which implements the Internet Checksum as a hash.Hash.
