Comment # 18 on bug 1018839 from Ruediger Oertel

fw download seems to work but apparently there is no way to acutally activate
this firmware (or the firmware is not in a format this drive accepts):

# nvme fw-download /dev/nvme0 --fw=/root/8DV101H0.bin 
Firmware download success
ibs-arm-1:~ # nvme fw-activate /dev/nvme0 -s 0 -a 1
NVME Admin command error:FIRMWARE_IMAGE(107)
ibs-arm-1:~ # nvme fw-activate /dev/nvme0 -s 0 -a 0
NVME Admin command error:INVALID_FIELD(2)
ibs-arm-1:~ # nvme fw-activate /dev/nvme0 -s 0 -a 2
Success activating firmware action:2 slot:0

okay, action 2 succeeds, but that does not involve the newly
uploaded/downloaded
firmware.

and fw-log tells me we still run the old firmware, no matter if we
just reset the nvme device or reset the whole system.

ibs-arm-1:~ # echo 1 > /sys/class/nvme/nvme0/device/reset
ibs-arm-1:~ # nvme fw-log /dev/nvme0
Firmware Log for device:nvme0
afi  : 0x1
frs1 : 0x3046313031564438 (8DV101F0)

(BTW: it is /sys/class/nvme/nvme0 and not /sys/class/misc/nvme0 these days
apparently ... ;)
