+ * The u-boot networking stack is a little weird. It seems like the

+ * buffers allocated by the core isn't very practical to use. We'll
+ * allocate our own, but we need one such buffer in case a packet
+ * wraps around the DMA ring so that we have to copy it.
+ *
+ * Therefore, define CFG_RX_ETH_BUFFER to 1 in the board-specific
+ * configuration header. This way, the core allocates one RX buffer
+ * and one TX buffer, each of which can hold a ethernet packet of
+ * maximum size.
+ *
+ * For some reason, the networking core unconditionally specifies a
+ * 32-byte packet "alignment" (which really should be called
+ * "padding"). MACB shouldn't need that, but we'll refrain from any
