Tushar,
Thanks for the erratum.
It seems like this might be the same problem as the 82574 since eeprom fix for
the825 74 says:
"The value at offset 0x001e (58) has bit 1 unset. This enables the problematic
power saving feature. In this case, the EEPROM needs to read "5a" at offset
0x001e."
The 82579 erratum states:
"The Intel 82579 Gigabit Ethernet Controller may experience packet Loss at 100
Mbps and 1 Gbps speeds when the link between the Intel 82579 Gigabit Ethernet
Controller and the PCH Integrated LAN Controller is exiting the Low Power Link
(K1) State."
I am betting that if there is a way to shut off power saving for the 82574 in
the eeprom that there would be a way to do a similar type of work around for
the 82579.
Thanks,
Joe
