How about you work on one driver at a time, to learn about the
processes for submitting to the Linux kernel.

https://www.kernel.org/doc/html/latest/process/maintainer-netdev.html#netdev-faq

https://docs.kernel.org/process/submitting-patches.html

https://www.kernel.org/doc/html/latest/process/coding-style.html

I would also think about why Intel has not submitted this code before?
Maybe because it does things the wrong way? Please look at how other
Ethernet drivers support firmware. Is it the same? It might be you
need to throw away this code and reimplement it to mainline standards,
maybe using devlink flash, or ethtool -f.

One additional question. Is the firmware part of linux-firmware? Given
this is Intel, i expect the firmware is distributeable, but have they
distributed it?
