I think I may have said it at one point. Note there's a difference between
"possible" and "easy"! And it may not work quite as expected - in
particular, if the two IP addresses are on the same subnet, then the simple
"routing" that lwIP provides means that it will always send packets out the
first netif. And as for receiving packets, you will have to handle
differentiating which packets are which in the driver.
