'eth_drv.c' is not the hardware drivers - it's an interface between the stack and the physical driver. I think you can probably just write a "normal" network driver for your hardware and install it just like any other, regardless of the fact that it's not ethernet at the physical layer. The logical driver (eth_drv.c) only cares that your driver knows how to send and receive packets. > Thanks! > > > > Andrew Lunn <[EMAIL PROTECTED]> > Sent by: [EMAIL PROTECTED] > 29/11/2005 11:15 > > To > Birahim Larou Fall <[EMAIL PROTECTED]> > cc > Andrew Lunn <[EMAIL PROTECTED]>, eCos Discussion > <ecos-discuss@ecos.sourceware.org> > Subject > Re: [ECOS] Entry point of stack IP > > > > > > > On Tue, Nov 29, 2005 at 10:15:28AM +0100, Birahim Larou Fall wrote: > > It is more like PPP/SLIP.
