Re: [lwip-users] Two ethernet port with one mac address

[Sergio R. Caprile]

lwIP does not care about RMII, that is between your MAC controller and
your PHY controller. Whatever happens there is your driver's business.
Do you have two MAC controllers ? Or are you trying to handle two PHYs
with one MAC ? (Why would you do that ?)

1 IP 1 MAC 2 PHY: beyond my understanding, needs special driver.
1 IP 2 MAC 2 PHY: needs bridging driver.

Drivers are not a part of lwIP. You could perhaps find someone here
willing to help, though.
