                 Little testing has been done to make sure that different
                 device models from each vendor work correctly with the
                 fwdownload command.  A vendor name appearing in the supported
                 list means only that firmware of at least one device type
                 from that vendor has successfully been programmed with the
                 fwdownload command.  Extra caution should be taken when using
                 this command since there is no guarantee it will not break a
                 device from the listed vendors.  Ensure that you have a
                 recent backup of the data on the device before performing a
                 firmware update.

                 -f fw_image  Path to the firmware image file to be downloaded
                              to the specified device.

                 -y           Do not ask for confirmation.

                 -s           Run in simulation mode.  Packet sizes that will
                              be sent are shown, but no actual packet is sent
                              to the device.  No confirmation is asked in sim‐
                              ulation mode.

                 -v           Besides showing sense information in case of a
                              failure, the verbose option causes camcontrol to
                              output a line for every firmware segment that is
                              sent to the device by the fwdownload command --
                              the same as the ones shown in simulation mode.
