Hello Simon,

Also you can argue that buffer management is a reasonable thing to provide a method for. Using a buffer to receive a packet, sending that packet for processing, and retiring the buffer are all conceptually separate things. We could even consider (in the future!) supporting a buffer ring in the uclass since all of the drivers I have looked at have one.
Just in case: remember that some drivers use SRAM-based buffers while others use DDR-based buffers. Buffer management should support either use case. Also, there's more than just buffers; descriptors might be needed too -- whether they should be generalized or not, I have no clear idea, though.
Amicalement,
