Hey Marco,

I would definitely look at the SLIP netif. I've been using it and the current code works.

It is basically a point to point IP encapsulation with almost no overhead (1 byte). It assumes that both sides already know their IP configuration. So you can manually assign IP addresses to each radio station and then create a simple driver to connect to the right station according to destination IP address.

PPPoS is unfortunately not an option. It's basically still a
point-to-point-protocol with some overhead. We're not using dedicated
P2P connections; one single packet will go to a completely different
target than the very next packet.

It's a narrow bandwith application, there is no room for establishing
a PPPoS connection, sending the data packet, end the connection,
reestablish the connection to the next radio etc.

Back to my initial idea, will this be a reasonable way to do it?
