Recommended methods to upgrade firmware on HBAs

[Matthew Jacob]

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.
