Very nice work!  I too had been intending to work on this at some
nebulous date in the future, great to see it actually done and boards
ordered!

Quick question -- how are you handling MAC allocation?  Each module
comes with the MAC address on a sticker; the mainboard itself doesn't
have a MAC allocated to the BMC port until the module is installed.

In any case, we'll probably be switching away from the proprietary
modules for future work; great to see KiCad used here as well.
