The Firmware Image Download command may be submitted while other commands on the Admin Submission Queue or I/O Submission Queues are outstanding\&. The Firmware Image Download command copies the new firmware image (in whole or in part) to the controller\&. +.sp +The firmware image may be constructed of multiple pieces that are individually downloaded with separate Firmware Image Download commands\&. Each Firmware Image Download command includes a Dword Offset and Number of Dwords that specify a Dword range\&. The host software shall ensure that firmware pieces do not have Dword ranges that overlap\&. Firmware portions may be submitted out of order to the controller\&. +.sp +The new firmware image is not applied as part of the Firmware Image Download command\&. It is applied following a reset, where the image to apply and the firmware slot it should be committed to is specified with the Firmware Commit command (nvme fw\-commit <args>)\&. +.SH "OPTIONS" +.PP +\-f <firmware\-file>, \-\-fw=<firmware\-file> +.RS 4 +Required argument\&.
