^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) 		wrong during FPGA programming (something that the driver can't
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) 		fix) then userspace can know, i.e. if the firmware request
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) 		fails, that could be due to not being able to find the firmware

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) 		to get the FPGA into a known operating state.  It's a sequence,

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) 		by manufacturer; this is a superset.
