Hi Yacob,
I mean two MACs and two Phys. Actually one Phy is an Ethernet and the second is an Ethernet over VARAN (but for the stack it must look like a normal Ethernet Phy).

By Ethernet adaptor what do you mean? a. Two MAC and two Phys or b. One MAC and two Phys Sincerely, Yacob Hassidim.

I already have an implementation with only one, so I already have an experience with LWIP stack. Now I need to understand how the LWIP is designed to be used in case of two (or more) Ethernet adapters. It is clear that I need to use two separated netif structure for each adapter. What I’m wandering now is how to connect to it the initialized udp_pcb and tcp_pcb (they are different for both interfaces). How I can connect the pcbs to the netif-structures? If I cannot access the pcbs from netif-structure, then I need to add them like additional parameters to some functions… Sorry for this question, but I by reading in Internet I couldn’t find a good explanation how LWIP must be used in such case. So please, give me some hints… Best regards! Simeon
