Hi Sir :
I really appreciate your reply!
As you say “If your chip outputs data for a TCP/IP 'socket', you don't need
lwIP”.
And how can I pass my data to socket?
Best regards,
Marcus

You do need a netif anyway
You will write a driver for your SPI chip.
If your chip outputs Ethernet frames, it is in no way different from
other connection options (parallel, on chip)
If your chip outputs IP datatagrams, you'll have to enter the stack on a
higher level function, and I can't help you here.
If your chip outputs data for a TCP/IP 'socket', you don't need lwIP.
