The UFM subsystem today has the ability to report information about modules. We've envisioned that it should be able to read and write module information. This takes the first step towards that by adding a few concrete things:

• Adds a new UFM capability value to indicate the ability to read images
• Adds a new entry point to the UFM ops structure to indicate that we can read an image
• Adds support for fwflash for a UFM background so that we can list firmware images and read them from supported devices

On a system with some additional UFM devices, here's an example of the UFM output in fwflash. The first is from a system with a single M.2 and igb device.

Device[0] /devices/pci@0,0/pci1022,1483@3,2/pci8086,390d@0
Class [ufm]
        Vendor: Intel Corporation
        Device: SSD 660P Series
        Capabilities: Report
        Image 0: Firmware
            Slot 0 (-|w|a): 002C    
            Slot 1 (-|w|-): 002C    

Device[1] /devices/pci@3d,0/pci1022,1483@3,1/pci1849,1521@0
Class [ufm]
        Vendor: Intel Corporation
        Device: I350 Gigabit Network Connection
        Capabilities: Report, Read Image
        Image 0: NVM
            Slot 0 (r|w|a): 1.69

This next example shows how it fits into a system with a number of SATA/SAS devices:

$ pfexec fwflash -l
