- Fix to ioctl path in which the length could be 0 which means no data in/out from LSI. - Fix to ioctl path in which the data in the sense data space of the ioctl packet is a really a pointer to some location in user-space. From LSI re-worked a bit by me. - Add HW support for next gen cards from LSI. Thanks to LSI for their support! Submitted by: jhb, LSI MFC after: 3 days
