upstream vendors provided me with a git repo of ALL necessary layers
with the understanding that I'd clone the repo locally and disable
network access, using only our local cloned repo in dl_mirror/

The files in dl_mirror are either raw tarballs, gitshallow, or
gitsmshallow. I've touched the .done file for all of them.

After removing all state cache and attempting a clean rebuild I'm
getting a do_fetch failure on a recipe for one of the vendor specific
fragments.

ERROR: XXX-pll-ctrl-git-r0 do_fetch: Network access disabled through

I need to force yocto to ONLY use or attempt to use dl_mirror/
content...regardless of what the SRC_URI is in the recipe. Not clear
on why "git clone --mirror" still references upstream repo

How to accomplish bombproof local dl_mirror/ reference only?
