Support for the new hashing algorithms in ZFS was introduced in r289422 However it was disconnected because FreeBSD lacked implementations of SHA-512 (truncated to 256 bits), and Skein. These implementations were introduced in r300921 and r300966 respectively This commit connects them to ZFS and enabled these new checksum algorithms This new algorithms are not supported by the boot blocks, so do not use them on your root dataset if you boot from ZFS.
