+ * The Pegasus chip uses four USB "endpoints" to provide 10/100 ethernet
+ * support: the control endpoint for reading/writing registers, burst
+ * read endpoint for packet reception, burst write for packet transmission
+ * and one for "interrupts." The chip uses the same RX filter scheme
+ * as the other ADMtek ethernet parts: one perfect filter entry for the
+ * the station address and a 64-bit multicast hash table. The chip supports
+ * both MII and HomePNA attachments.
+ *
+ * Since the maximum data transfer speed of USB is supposed to be 12Mbps,
+ * you're never really going to get 100Mbps speeds from this device. I
+ * think the idea is to allow the device to connect to 10 or 100Mbps
+ * networks, not necessarily to provide 100Mbps performance. Also, since
+ * the controller uses an external PHY chip, it's possible that board
+ * designers might simply choose a 10Mbps PHY.
+ *
+ * Registers are accessed using usbd_do_request(). Packet transfers are
+ * done using usbd_transfer() and friends.
