[ECOS]Eth driver to NPE on xscale ixp425
Fri Sep 24 13:32:00 GMT 2004
I have more question about driver :
1. Why is rx and tx_callback registerd two times ( in npe_init and npe_start)
- I try to add driver to eCos multithread application.
2. NPE Mh is initialized in interrupt mode but in npe_poll is checked for
messages from the NPE. Is that correct ?
