SubjectIntel 82559 NIC corrupted EEPROM
Hello,

I have an EBC-2000T motherboard with 3 on-board Intel 82559 NICs.

http://www.intel.com/design/network/products/lan/controllers/82559.htm
http://www.adlinktech.com/PD/web/PD_detail.php?pid=213
http://www.intel.com/support/network/adapter/1000/linux/e100.htm

Running a 2.6.14 kernel, the e100 driver refuses to load because
it detects a corrupted EEPROM.

cf. e100_eeprom_load()

/* The checksum, stored in the last word, is calculated such that
* the sum of words should be 0xBABA */
checksum = le16_to_cpu(0xBABA - checksum);
if(checksum != nic->eeprom[nic->eeprom_wc - 1]) {
DPRINTK(PROBE, ERR, "EEPROM corrupted\n");
if (!eeprom_bad_csum_allow)
return -EAGAIN;
}

Several people have reported the same error. Intel's Auke Kok has
stated that ignoring the error is a BAD idea.

What tool is used to reprogram the EEPROM? ethtool?
I suppose I'll have to ask the manufacturer for an updated EEPROM?


# ethtool -e eth0
Cannot get EEPROM data: Operation not supported

I'm not sure why I can't dump the contents of the EEPROM.
Does the driver need to be loaded?

On a totally unrelated note, does the 82559 support VLAN tagging?
(I believe the driver supports it.)

Thanks for reading this far.

Please note, email address is a bit-bucket.
I do monitor the mailing list.

Regards.

John
