Hi,
I received the following error in the kernel log while trying to use the
3Ware command line management utility (tw_cli):
ioctl32(tw_cli:10922): Unknown cmd fd(3) cmd(0000001f){00} arg(081892d0)
on /dev/twe0
The following patch against 193 adds the missing ioctls and allows the
application to work. I'm not sure if this is the proper approach, but
it works for all of my testing.
Mike
