Generates adapter failure interrupt. 502 * Requires TX Reset or Global Reset command to recover. 503 * Disables Transmitter. 504 * 9-8: Unassigned. 505 * 7-0: Built in self test bits for the RX and TX FIFO's. 506 */ 507 #define FIFOS_RX_RECEIVING (u_int16_t) 0x8000 508 #define FIFOS_RX_UNDERRUN (u_int16_t) 0x2000 509 #define FIFOS_RX_STATUS_OVERRUN (u_int16_t) 0x1000 510 #define FIFOS_RX_OVERRUN (u_int16_t) 0x0800 511 #define FIFOS_TX_OVERRUN (u_int16_t) 0x0400 512 513 /* 514 * ISA/eisa CONFIG_CNTRL media-present bits. 515 */ 516 #define ELINK_W0_CC_AUI (1<<13) 517 #define ELINK_W0_CC_BNC (1<<12) 518 #define ELINK_W0_CC_UTP (1<<9) 519 #define ELINK_W0_CC_MEDIAMASK (ELINK_W0_CC_AUI|ELINK_W0_CC_BNC| \ 520 ELINK_W0_CC_UTP) 521 522 /* EEPROM state flags/commands */ 523 #define EEPROM_BUSY (1<<15) 524 #define EEPROM_TST_MODE (1<<14) 525 526 #define READ_EEPROM (1<<7) 527 528 /* For the RoadRunner chips... */ 529 #define WRITE_EEPROM_RR 0x100 530 #define READ_EEPROM_RR 0x200 531 #define ERASE_EEPROM_RR 0x300 532 533 /* window 4, MEDIA_STATUS bits */ 534 #define SQE_ENABLE 0x08 /* Enables SQE on AUI ports */ 535 #define JABBER_GUARD_ENABLE 0x40 536 #define LINKBEAT_ENABLE 0x80 537 #define DISABLE_UTP 0x0 538 #define LINKBEAT_DETECT 0x800 539 540 /* 541 * Misc defines for various things. 542 */ 543 #define TAG_ADAPTER 0xd0 544 #define ACTIVATE_ADAPTER_TO_CONFIG 0xff 545 #define ENABLE_DRQ_IRQ 0x0001 546 #define MFG_ID 0x506d /* `TCM' */ 547 #define PROD_ID_3C509 0x5090 /* 509[0-f] */ 548 #define GO_WINDOW(x) bus_space_write_2(sc->sc_iot, \ 549 sc->sc_ioh, ELINK_COMMAND, WINDOW_SELECT|x) 550 551 552 /* Used to probe for large-packet support. */ 553 #define ELINK_LARGEWIN_PROBE ELINK_THRESH_DISABLE 554 #define ELINK_LARGEWIN_MASK 0xffc 555
