Ethernet and eth driver problem

Now, I test ethernet and ethernet driver on sl8082BX module. It can’t invoke the interrupt handle when an interrupt occurs. What is wrong with the modules? Thank you.

Can I use ethernet on sl8082???

Hi, I am working ethernet driver on sl8082BX module. I am facing issue with opening any bearer. I got to know that To open, configure and start the related bearer first the driver has to be registered with the wip_drvSubscribe () API. But i did not get any information regarding this API wip_drvSubscribe (). Please let me how to subscribe to driver and how to open Ethernet bearer. Thanks for advance.

Hi, I am facing issue with opening any bearer(UART Bearer, GSM, Ethernet bearer etc).
/* Open the UART bearer */
bearerRet = wip_bearerOpen ( &br, PPP_BEARER, cbEvhBearer, NULL );

It is returning -44. I dont know -44 does mean.
