So this confirms what I was suspecting. The 10M you see at first is the "default" state of the ethernet card where it's watching for the wake-on-lan signal. Once the kernel boots and initializes the card, the card tries to auto-negotiate. This seems to be failing due to some interaction between the pi's network device and this one.
If it is an issue of auto negotiation one could also try using nmcli to set
802-3-ethernet.auto-negotiate: to no and as well as the appropriate settings for
802-3-ethernet.speed: 802-3-ethernet.duplex:
in the connection settings.
I don't think that would work. The problem is most likely the MDI-X negotiation which neither card supports a setting for. I suspect a crossover cable would also resolve the problem.
