freebsd stable - Jan 2021 - ses device over T-SGPIO

I've never used any tool with SGPIO.  The hardware simply isn't powerful
enough to be useful.  sesutil works, in theory, to control the LEDs.  But
it's of limited usefulness since there's no way to tell which drives are
installed in which slots.

For me sesutil failed w/ "No SES device found"
