Message:

total rewrite, supports killing fwcf once-off and even adding
a custom pre-made fwcf image (for example with the host tools
that get built now) for certain routers (at the moment, only
Asus WL-500gP, because I need to watch more dmesg pr0n in order
to add this for the other devices).

Support for other devices and maybe even generating the fwcf
image from a directory tree using the host tools will be added
at a later time.

    42 
    43 1) connect your PC to the LAN port
    44 2) be sure your link is up and has an address in the
    45    range 192.168.1.0/24 but other than 192.168.1.1,
    46    or specify an IP address where to flash to

     170        do not have to be regenerated each time the device starts.
