    kernel: add module support Solarflare network adapter
    
    According to Solarflare user guide
    it is recommended to install lm-sensors and
    use the following command to obtain adapter health info
    
    $ sensors | grep sfc
    sfc pci 0400
    sfc pci 0401
    
    $ sensors sfc pci 0400
    sfc pci 0400
    Adapter: PCI adapter
