I thought I replied to the whole list, not just the sender, sorry for
the repeat....
(full config is attached)
As a module, the system booted up but did not probe the module.
This may be from a variety of issues, not limited to the fact I am still
rolling this distro from scratch, and not all of the tools are 100%
working yet.
I'm having some issues with gcc/gdb so I have a large number of
debugging options turned on in the kernel as well.
When the module is loaded with insmod:

When I pulled the plug I did not get the crash..
When I plugged it back in, I did not get a dmesg/kernel line for the
link.
I bound the IP addresses to both, and did a ping test to the default
gateway, resulting in:
(I promise the network is properly configured)

Upon pulling the cord out of the switch **after** the IP address was
bound, we are back to this:

Once the IPs are bound, a link loss pops the message:
