Jifl, the only concerns i see are : 1. Difference in the data types of the packets, which a function in the middle will have to sort. 2. IAR TCP/IP calls the input function of the lower layer, whereas in lwip lower layer calls the upper layers. i.e. PPP calls IP in lwip for in-coming data and IP calls ethernet(or PPP) in IAR.
As for including lwip with IAR TCP/IP i'm already including files necesary for PPP from the lwip stack. I'm hoping to removed IPv4 and TCP part of lwip in my implementation. Am i doing a flaw?
