- 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);
I do plan to rename the function, though.
OK.
