+ * Driver for Xilinx TEMAC Ethernet device

+ * Copyright (c) 2008 Nissin Systems Co., Ltd.,  Yoshio Kashiwagi

+ * Copyright (c) 2008-2009 Secret Lab Technologies Ltd.
+ *
+ * This is a driver for the Xilinx ll_temac ipcore which is often used
+ * in the Virtex and Spartan series of chips.
+ *
+ * Notes:
+ * - The ll_temac hardware uses indirect access for many of the TEMAC
+ *   registers, include the MDIO bus.  However, indirect access to MDIO
+ *   registers take considerably more clock cycles than to TEMAC registers.
+ *   MDIO accesses are long, so threads doing them should probably sleep
+ *   rather than busywait.  However, since only one indirect access can be
+ *   in progress at any given time, that means that *all* indirect accesses
+ *   could end up sleeping (to wait for an MDIO access to complete).
+ *   Fortunately none of the indirect accesses are on the 'hot' path for tx
+ *   or rx, so this should be okay.
+ *
+ * TODO:
+ * - Fix driver to work on more than just Virtex5.  Right now the driver
+ *   assumes that the locallink DMA registers are accessed via DCR
+ *   instructions.
+ * - Factor out locallink DMA code into separate driver
+ * - Fix multicast assignment.
+ * - Fix support for hardware checksumming.
+ * - Testing.  Lots and lots of testing.
