FreeBSD no longer uses optimized routines since state of the art network
interface controllers do this checksum stuff in hardware.
NetBSD has optimized variants, but the APIs differ. They also have the
advertising clause in their license.
I don't have time to write optimized assembler code myself at the moment.
