[ECOS] 82559 Self Test failure

[Cristiano Pereira]

Hi again,

If I comment out the Self Test piece of code I get another error in the 
function i82559_configure(). Seems like whenever I'm polling memory for 
checking some status I'm not getting the right result. The error happens in 
this part of the code:

// Default values from the Intel Manual
    config_bytes = ccs + CFG_BYTES;

    config_bytes[0]=0x13;
    config_bytes[1]=0xc;
    config_bytes[2]=0x0;
    config_bytes[3]=0x0;
    config_bytes[4]=0x0;
    config_bytes[5]=0x0;
    config_bytes[6]=0x32 | (promisc ? 0x80 : 0x00); //   | 0x32 for small 
stats,
    config_bytes[7]=0x00 | (promisc ? 0x00 : 0x01); //\  | 0x12 for stats 
with P
AUSE stats
    config_bytes[8]=0x01; // [7]:discard short frames  \ | 0x16 for PAUSE + 
TCO
stats
    config_bytes[9]=0x0;
    config_bytes[10]=0x28;
    config_bytes[11]=0x0;
    config_bytes[12]=0x60;
    config_bytes[13]=0x0;          // arp
    config_bytes[14]=0x0;          // arp

    config_bytes[15]=0x80 | (promisc ? 1 : 0); // 0x81: promiscuous mode set
                                               // 0x80: normal mode
    config_bytes[16]=0x0;
    config_bytes[17]=0x40;
    config_bytes[18]=0x72 | (oversized ? 8 : 0); // Keep the Padding Enable 
bit

    // Let chip read configuration
    wait_for_cmd_done(ioaddr, WAIT_CU);

    OUTL(VIRT_TO_BUS(ccs), ioaddr + SCBPointer);
    OUTW(SCB_M | CU_START, ioaddr + SCBCmd);

    // ...and wait for it to complete operation
    count = 10000;
    do {
      udelay(1);
      READMEM16(ccs + CFG_STATUS, status);
    } while (0 == (status & CFG_STATUS_C) && (count-- > 0));

    // Check status
    if ((status & (CFG_STATUS_C | CFG_STATUS_OK))
        != (CFG_STATUS_C | CFG_STATUS_OK)) {
        // Failed!
#ifdef DEBUG
        os_printf("%s:%d Config update failed\n", __FUNCTION__, __LINE__);
#endif
        return 1;
    }

The function prints the message right above and returns.

Thanks again,
Cristiano.
