// CVS Revision History
//
// $Log: not supported by cvs2svn $
// Revision 1.22  2002/09/04 18:36:49  mohor
// Defines for control registers added (ETH_TXCTRL and ETH_RXCTRL).
//
// Revision 1.21  2002/08/16 22:09:47  mohor
// Defines for register width added. mii_rst signal in MIIMODER register
// changed.
//
// Revision 1.20  2002/08/14 19:31:48  mohor
// Register TX_BD_NUM is changed so it contains value of the Tx buffer descriptors. No
// need to multiply or devide any more.
//
// Revision 1.19  2002/07/23 15:28:31  mohor
// Ram , used for BDs changed from generic_spram to eth_spram_256x32.
//
// Revision 1.18  2002/05/03 10:15:50  mohor
// Outputs registered. Reset changed for eth_wishbone module.
//
// Revision 1.17  2002/04/24 08:52:19  mohor
// Compiler directives added. Tx and Rx fifo size incremented. A "late collision"
// bug fixed.
//
// Revision 1.16  2002/03/19 12:53:29  mohor
// Some defines that are used in testbench only were moved to tb_eth_defines.v
// file.
//
// Revision 1.15  2002/02/26 16:11:32  mohor
// Number of interrupts changed
//
// Revision 1.14  2002/02/16 14:03:44  mohor
// Registered trimmed. Unused registers removed.
//
// Revision 1.13  2002/02/16 13:06:33  mohor
// EXTERNAL_DMA used instead of WISHBONE_DMA.
//
// Revision 1.12  2002/02/15 10:58:31  mohor
// Changed that were lost with last update put back to the file.
//
// Revision 1.11  2002/02/14 20:19:41  billditt
// Modified for Address Checking,
// addition of eth_addrcheck.v
//
// Revision 1.10  2002/02/12 17:01:19  mohor
// HASH0 and HASH1 registers added. 
 
// Revision 1.9  2002/02/08 16:21:54  mohor
// Rx status is written back to the BD.
//
// Revision 1.8  2002/02/05 16:44:38  mohor
// Both rx and tx part are finished. Tested with wb_clk_i between 10 and 200
// MHz. Statuses, overrun, control frame transmission and reception still  need
// to be fixed.
//
// Revision 1.7  2002/01/23 10:28:16  mohor
// Link in the header changed.
//
// Revision 1.6  2001/12/05 15:00:16  mohor
// RX_BD_NUM changed to TX_BD_NUM (holds number of TX descriptors
// instead of the number of RX descriptors).
//
// Revision 1.5  2001/12/05 10:21:37  mohor
// ETH_RX_BD_ADR register deleted. ETH_RX_BD_NUM is used instead.
//
// Revision 1.4  2001/11/13 14:23:56  mohor
// Generic memory model is used. Defines are changed for the same reason.
//
// Revision 1.3  2001/10/18 12:07:11  mohor
// Status signals changed, Adress decoding changed, interrupt controller
// added.
//
// Revision 1.2  2001/09/24 15:02:56  mohor
// Defines changed (All precede with ETH_). Small changes because some
// tools generate warnings when two operands are together. Synchronization
// between two clocks domains in eth_wishbonedma.v is changed (due to ASIC
// demands).
//
// Revision 1.1  2001/08/06 14:44:29  mohor
// A define FPGA added to select between Artisan RAM (for ASIC) and Block Ram (For Virtex).
// Include files fixed to contain no path.
// File names and module names changed ta have a eth_ prologue in the name.
// File eth_timescale.v is used to define timescale
// All pin names on the top module are changed to contain _I, _O or _OE at the end.
// Bidirectional signal MDIO is changed to three signals (Mdc_O, Mdi_I, Mdo_O
// and Mdo_OE. The bidirectional signal must be created on the top level. This
// is done due to the ASIC tools.
//
// Revision 1.1  2001/07/30 21:23:42  mohor
// Directory structure changed. Files checked and joind together.
