>Description:
When trying to do a zfs send/receive from FreeBSD/amd64 to FreBSD/sparc64 the receiving box paniced with "zfs_ace_byteswap:112: TODO"

I recompiled kernels without the TODO-#ifdef, tried several send/receives in both directions and everything seems to be fine. Maybe this code can be enabled also on FreeBSD?
>How-To-Repeat:
Do a zfs send/receive from a BE to a LE box or vice versa.
>Fix:
Comment out the TODO-#ifdef in /sys/cddl/contrib/opensolaris/uts/common/fs/zfs/zfs_byteswap.c
