iam sending and recieving data packets through spi only my slave automatically converts to ethernet which is recieved in the form spi slave is IC is jsz885snl 

could you send any resources to understand lwip protocol how data will send and which order data will send so that i can understand how the lwip stack willl work

These resources can be helpful to become familiar with lwip:
Brief Introduction to LwIP stack in MCUXpresso SDK - NXP Community
lwIP Wiki | Fandom

Regarding SPI to ENET, there is no specific example of both protocols combined, however, you can merge the two protocols in your application by referring to the separate examples of the protocols.

Hello
I hope you are well.

I suggest you take as reference the SPI and ENET examples from the SDK.
What are you trying to implement? Are you trying to receive data from the SPI interface and send the received data through ethernet?

Best regards,
Omar
