* Gianfar Ethernet Driver
* B-V +1.62
*
* Theory of operation
- * This driver is designed for the Triple-speed Ethernet
- * controllers on the Freescale 8540/8560 integrated processors,
- * as well as the Fast Ethernet Controller on the 8540.
- *
+ * This driver is designed for the non-CPM ethernet controllers
+ * on the 85xx and 83xx family of integrated processors
+ *
* The driver is initialized through platform_device. Structures which
* define the configuration needed by the board are defined in a
* board structure in arch/ppc/platforms (though I do not
* discount the possibility that other architectures could one
- * day be supported. One assumption the driver currently makes
- * is that the PHY is configured in such a way to advertise all
- * capabilities. This is a sensible default, and on certain
- * PHYs, changing this default encounters substantial errata
- * issues. Future versions may remove this requirement, but for
- * now, it is best for the firmware to ensure this is the case.
+ * day be supported.
*
* The Gianfar Ethernet Controller uses a ring of buffer
* descriptors. The beginning is indicated by a register
- * pointing to the physical address of the start of the ring.
- * The end is determined by a "wrap" bit being set in the
+ * pointing to the physical address of the start of the ring.
+ * The end is determined by a "wrap" bit being set in the
* last descriptor of the ring.
*
* When a packet is received, the RXF bit in the
- * IEVENT register is set, triggering an interrupt when the
+ * IEVENT register is set, triggering an interrupt when the
* corresponding bit in the IMASK register is also set (if
* interrupt coalescing is active, then the interrupt may not
* happen immediately, but will wait until either a set number
- * of frames or amount of time have passed.). In NAPI, the
+ * of frames or amount of time have passed). In NAPI, the
* interrupt handler will signal there is work to be done, and
* exit. Without NAPI, the packet(s) will be handled
* immediately. Both methods will start at the last known empty
- * descriptor, and process every subsequent descriptor until there

* are none left with data (NAPI will stop after a set number of
