I have a horrible hack to the twe driver to enable it to understand the
32 bit binary ioctl's. It was enough for me to run the CLI.
I was thinking about committing it, but I've been meaning to ask the
3ware folks for a native build, which would be much better. Maybe they
do a build so I won't have to commit this. I've given this diff to all the people
that have asked.
Their management stuff generally passes opaque data blobs through
from the cli/3dm to the firmware. We don't need to see what it is.
Anyway, the diff:
