Hi,

In my application I’m going to support two Ethernet adapters. 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
