Subject: Re: Intel 82559 NIC corrupted EEPROM
Hello all,
[ E-mail address is a bit-bucket. I *do* monitor the mailing lists. ]
I will try and summarize the problem as I understand it at this point.
I've written two messages so far:
http://groups.google.com/group/linux.kernel/msg/3a05d819c66474db
http://groups.google.com/group/linux.kernel/msg/391aebbb3dfd6039
And here is a link to the complete thread:
http://lkml.org/lkml/fancy/2006/11/3/124
I have a motherboard with three on-board 82559 NICs.
o eepro100.ko properly initializes all three NICs
o e100.ko fails to initialize one of them
NOTE: With kernel 2.6.14, e100.ko fails to initialize the NIC with MAC
address 00:30:64:04:E6:E4. With kernel 2.6.18 e100.ko fails to
initialize the NIC with MAC address 00:30:64:04:E6:E5.
The problem is not an incorrect checksum. (Donald Becker's dump utility
reports a correct checksum for all three NICs.) The problem seems to be
that e100.ko fails to read the contents of one of the EEPROMs.

These tests were performed on a 2.6.14 kernel. I hacked
e100_eeprom_load() to return 0 even when the checksum
fails. Thus the driver did not refuse to load, and I was
able to use ethtool to dump the contents of the 3 EEPROMs.
Here are additional examples running a 2.6.18.1-hrt kernel.

No interrupt sources are pending.
The transmit unit state is 'Idle'.
The receive unit state is 'Idle'.
This status is unusual for an activated interface.

Primary interface chip i82555 PHY #1.
Sleep mode is enabled. This is not recommended.
Under high load the card may not respond to
PCI requests, and thus cause a master abort.
To clear sleep mode use the '-G 0 -w -w -f' options.

On a related note, I am concerned by this message:

Intel 82559 EEPROM Map and Programming Information (AP-394) states:
http://www.intel.com/design/network/applnots/ap394.htm
The Standby Enable bit enables the 82559 to enter standby mode. When
this bit equals 1b, the 82559 is able to recognize an idle state and can
enter standby mode (some internal clocks are stopped for power saving
purposes). The 82559 does not require a PCI clock signal in standby
mode. If this bit equals 0b, the idle recognition circuit is disabled
and the 82559 always remains in an active state. Thus, the 82559 always
requests PCI CLK using the Clockrun mechanism.
Auke, do you agree with Donald Becker's warning?
If I disable STB, the NICs will waste a bit more power when idle,
is that correct? Are there other implications?
Thanks for reading this far!
John
