vdev_id: new slot type ses
This extends vdev_id to support a new slot type, ses, for SCSI Enclosure Services. With slot type ses, the disk slot numbers are determined by using the device slot number reported by sg_ses for the device with matching SAS address, found by querying all available enclosures. This is primarily of use on systems with a deficient driver omitting support for bay_identifier in /sys/devices. In my testing, I found that the existing slot types of port and id were not stable across disk replacement, so an alternative was required. Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Simon Guest <[email protected]> Closes #6956
