DAC1100 RAID controller

Here is a patch for this problem report.
The bug is in the subr's `mlxd_foreach_ctrlr' and
`mlxd_find_ctrlr_search', both in interface.c. Both of these
subroutines use `ioctl(fd, MLX_NEXT_CHILD, &i)' to iterate over the
configured mlxd(4) devices. However, in FreeBSD 4.10-RELEASE, this
simply sets i to 0.
I have replaced this code with a simple-minded loop from i=0 to 63,
which is a large enough loop to find any devices on the RAID
controllers supported by mlxd(4). It is likely that there is a more
clever fix, but this does the job for me. If anybody has a better
fix, I would be happy to test it.
Attached is a patch file for /usr/src/usr.sbin/mlxcontrol/interface.c
in FreeBSD 4.10-RELEASE.
