// $Log: not supported by cvs2svn $

// Revision 1.28  2004/04/26 15:26:23  igorm

// - Bug connected to the TX_BD_NUM_Wr signal fixed (bug came in with the

//   previous update of the core.

// - TxBDAddress is set to 0 after the TX is enabled in the MODER register.

// - RxBDAddress is set to r_TxBDNum<<1 after the RX is enabled in the MODER

//   register. (thanks to Mathias and Torbjorn)

// - Multicast reception was fixed. Thanks to Ulrich Gries

//

// Revision 1.27  2004/04/26 11:42:17  igorm

// TX_BD_NUM_Wr error fixed. Error was entered with the last check-in.

//

// Revision 1.26  2003/11/12 18:24:59  tadejm

// WISHBONE slave changed and tested from only 32-bit accesss to byte access.

//

// Revision 1.25  2003/04/18 16:26:25  mohor

// RxBDAddress was updated also when value to r_TxBDNum was written with

// greater value than allowed.

//

// Revision 1.24  2002/11/22 01:57:06  mohor

// Rx Flow control fixed. CF flag added to the RX buffer descriptor. RxAbort

// synchronized.

//

// Revision 1.23  2002/11/19 18:13:49  mohor

// r_MiiMRst is not used for resetting the MIIM module. wb_rst used instead.

//

// Revision 1.22  2002/11/14 18:37:20  mohor

// r_Rst signal does not reset any module any more and is removed from the design.

//

// Revision 1.21  2002/09/10 10:35:23  mohor

// Ethernet debug registers removed.

//

// Revision 1.20  2002/09/04 18:40:25  mohor

// ETH_TXCTRL and ETH_RXCTRL registers added. Interrupts related to

// the control frames connected.

//

// Revision 1.19  2002/08/19 16:01:40  mohor

// Only values smaller or equal to 0x80 can be written to TX_BD_NUM register.

// r_TxEn and r_RxEn depend on the limit values of the TX_BD_NUMOut.

//

// Revision 1.18  2002/08/16 22:28:23  mohor

// Syntax error fixed.

//

// Revision 1.17  2002/08/16 22:23:03  mohor

// Syntax error fixed.

//

// Revision 1.16  2002/08/16 22:14:22  mohor

// Synchronous reset added to all registers. Defines used for width. r_MiiMRst

// changed from bit position 10 to 9.

//

// Revision 1.15  2002/08/14 18:26:37  mohor

// LinkFailRegister is reflecting the status of the PHY's link fail status bit.

//

// Revision 1.14  2002/04/22 14:03:44  mohor

// Interrupts are visible in the ETH_INT_SOURCE regardless if they are enabled

// or not.

//

// Revision 1.13  2002/02/26 16:18:09  mohor

// Reset values are passed to registers through parameters

//

// Revision 1.12  2002/02/17 13:23:42  mohor

// Define missmatch fixed.

//

// Revision 1.11  2002/02/16 14:03:44  mohor

// Registered trimmed. Unused registers removed.

//

// Revision 1.10  2002/02/15 11:08:25  mohor

// File format fixed a bit.

//

// Revision 1.9  2002/02/14 20:19:41  billditt

// Modified for Address Checking,

// addition of eth_addrcheck.v

//

// Revision 1.8  2002/02/12 17:01:19  mohor

// HASH0 and HASH1 registers added. 

// 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 10:22:19  mohor

// ETH_RX_BD_ADR register deleted. ETH_RX_BD_NUM is used instead.

//

// Revision 1.4  2001/10/19 08:43:51  mohor

// eth_timescale.v changed to timescale.v This is done because of the

// simulation of the few cores in a one joined project.

//

// 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 1.2  2001/08/02 09:25:31  mohor

// Unconnected signals are now connected.

//

// Revision 1.1  2001/07/30 21:23:42  mohor

// Directory structure changed. Files checked and joind together.
