|
- *
|
|
|
- * Date Description of Change BY
|
|
|
- * --------- --------------------- ---
|
|
|
- * 05-May-99 Created MKW
|
|
|
- * 27-Jun-99 Clean up JWB
|
|
|
- * 16-Jul-99 Added MAL error recovery and better IP packet handling MKW
|
|
|
- * 29-Jul-99 Added Full duplex support MKW
|
|
|
- * 06-Aug-99 Changed names for Mal CR reg MKW
|
|
|
- * 23-Aug-99 Turned off SYE when running at 10Mbs MKW
|
|
|
- * 24-Aug-99 Marked descriptor empty after call_xlc MKW
|
|
|
- * 07-Sep-99 Set MAL RX buffer size reg to ENET_MAX_MTU_ALIGNED / 16 MCG
|
|
|
- * to avoid chaining maximum sized packets. Push starting
|
|
|
- * RX descriptor address up to the next cache line boundary.
|
|
|
- * 16-Jan-00 Added support for booting with IP of 0x0 MKW
|
|
|
- * 15-Mar-00 Updated enetInit() to enable broadcast addresses in the
|
|
|
- * EMAC_RXM register. JWB
|
|
|
- * 12-Mar-01 anne-sophie.harnois@nextream.fr
|
|
|
- * - Variables are compatible with those already defined in
|
|
|
- * include/net.h
|
|
|
- * - Receive buffer descriptor ring is used to send buffers
|
|
|
- * to the user
|
|
|
- * - Info print about send/received/handled packet number if
|
|
|
- * INFO_405_ENET is set
|
|
|
- * 17-Apr-01 stefan.roese@esd-electronics.com
|
|
|
- * - MAL reset in "eth_halt" included
|
|
|
- * - Enet speed and duplex output now in one line
|
|
|
- * 08-May-01 stefan.roese@esd-electronics.com
|
|
|
- * - MAL error handling added (eth_init called again)
|
|
|
- * 13-Nov-01 stefan.roese@esd-electronics.com
|
|
|
- * - Set IST bit in EMAC_M1 reg upon 100MBit or full duplex
|
|
|
- * 04-Jan-02 stefan.roese@esd-electronics.com
|
|
|
- * - Wait for PHY auto negotiation to complete added
|
|
|
- * 06-Feb-02 stefan.roese@esd-electronics.com
|
|
|
- * - Bug fixed in waiting for auto negotiation to complete
|
|
|
- * 26-Feb-02 stefan.roese@esd-electronics.com
|
|
|
- * - rx and tx buffer descriptors now allocated (no fixed address
|
|
|
- * used anymore)
|
|
|
- * 17-Jun-02 stefan.roese@esd-electronics.com
|
|
|
- * - MAL error debug printf 'M' removed (rx de interrupt may
|
|
|
- * occur upon many incoming packets with only 4 rx buffers).
|
|
|
- * 21-Nov-03 pavel.bartusek@sysgo.com
|
|
|
- * - set ZMII bridge speed on 440
|
