Re: [lwip-users] lwip port for LPC17xx micros

[FreeRTOS Info]

Hi again,

The drivers in FreeRTOS are interrupt (and I think DMA (?)) driven.  The
driver moves a packet into a buffer pointed to by a chain of DMA
descriptors, thats it.  I don't see why the driver would not be agnostic
of the stack it is being used with - the packets coming in off the
network will be the same - the reception and buffering of the packets by
the DMA will be the same - only how the packets are read from the
buffers by the stack will be different and that is not part of the
driver but part of the stack.


Regards,
Richard.
