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 * EMAC0_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 EMAC0_MR1 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). *-----------------------------------------------------------------------------* * 17-Nov-03 travis.sawyer@sandburst.com * - ported from 405gp_enet.c to utilized upto 4 EMAC ports * in the 440GX.
