Daniel Barlow 7e2b0068e6 nixfmt-rfc-style
There is nothing in this commit except for the changes made by
nix-shell -p nixfmt-rfc-style --run "nixfmt ."

If this has mucked up your open branches then sorry about that. You
can probably nixfmt them to match before merging

*************
This output provides a FIT image for Zyxel NWA series
