The current firmware(9) mechanism might work for you. The QLogic FC/SCSI cards in FreeBSD use that for loading firmware images to download to the cards, albeit to just load and reset, to update flash. This allows the drivers themselves to request updates.
Note that the root filesystem has to be mounted for this mechanism to work.
Other mechanisms include ioctl mechanisms as per what the LSI cards do via the mpiutil and mfiutil programs.

Hi All, 1. What is the current recommended method for upgrading firmware for HBAs? 2. Is there a mechanism wherein the firmware binary can be provided as a separate file, which is then made accessible to the corresponding device driver during device initialization? 3. Is there a restriction on the size of driver.ko file? If not, is it acceptable to provide the firmware as fw_file.c which is then compiled into the driver.
