fw: first attempt at writing a packet
...
Unsure if this is working, not sure if I have the tools to even know if
it does.
I could spend the time to actually write the packet by hand, or I could
probably spend ~2x the time and get smoltcp up.
Either way, the HW is validated, I am bringing up a link, I can talk to
LiteEth, so past here is driver stuff

...
Bus widths should now all be correct. (addresses and sizes in amaranth
take into account the granularity selection, so granularity acts like
two extra bits on the bus address line)
Also don't ignore a warning about undriven resets. Turns out that can
gate *everything* off in your design.

This was causing my nextpnr crash. I really do need to figure out how to

am doing this for a reason.
