- I think the recv() method should change before long. The
NetReceive() call should be made from the uclass since it is common to all drivers. Then the recv() method can return a packet if it finds one, but not submit it for processing
I looked into doing this and I think it may be more of a step backward. Currently devices can directly hand their DMA buffers to the network
stack.
With this change, most drivers would be forced to memcpy each packet
into
the supplied buffer.
I don't see why. The uclass can request the address and length of the
buffer.
int (*recv)(char **buffp, int **lenp);
That works... I think I'll return the length though. I don't see much value in having a pointer to the length.
int (*recv)(uchar **packetp);
