#17 Adaptec/Cogent quad & "Briain Damaged"

Special Notes

When using multiport cards with some (brain-damaged,
but technically not broken) PCI BIOSes the Tulip chips
are detected in reverse order. This isn't a problem if
where all chips have individual address EEPROMs, but
some multiport cards have only a single EEPROM on the
"first" chip which is now detected last. The current
work-around is implemented by loading the module
with the parameter 'reverse_probe=1' or compiling the
driver with '-DREVERSE_PROBE_ORDER=1'.
------------------------------------------------

I believe that I have run accross a case of such a
"Brain Damaged" BIOS with a FIC-PA2013 based on the VIA
Apollo MVP3 Chipset, an AMI BIOS and two Adaptec/Cogent
quad 10/100 ethernet controllers.

The first port on the first card (PCI slot 0,
eth0-eth3) works fine, but the last three ports report
"missing eeprom" with the "tulip-diag" program. All
the ports on the second card (PCI slot 1, eth4-eth7)
work excellent.

The problem is that the "reverse_probe=1" option is no
longer in the 2.4 "tulip" driver. I understand that
all the PCI stuff was moved out of the individual NIC
drivers to a common "pci-scan" routine to facilitate
cardbus in 2.4, but could there be some way to still
implement this in the driver or will this bug report
have to be submitted to the PCI guys? If the case is
the latter, to whom should I report this to?

Here is the relevent data on my set-up:
