The patch will also decode SMBIOS slot number for NIC, and store in
the variable ID_NET_NAME_SMBIOS_SLOT. Systemd does not have a method
for naming ports on a multi-port card plugged into a slot.
Hmm, isn't this stuff the same as exported by the kernel as the
"index" field, i.e. SMBIOS Type 41? Can you elaborate on the relation
of that field and the stuff this patch adds?
The index is exported for embedded devices, but not add-in cards.
acpi_index may be exported for add-in cards, but generally not very
useful as it has a number like 17 or 24... no relation to the actual
physical slot where a NIC is located.
Quoting SMBIOS spec for Type 9 "Slot ID":
--><--
On a system that supports ACPI, identifies the value returned in the
_SUN object for this slot.
On a system that supports the PCI IRQ Routing Table Specification,
identifies the value present
in the Slot Number field of the PCI Interrupt Routing table entry that
is associated with this slot
--><--
Kernel already exports _SUN when system supports it; and other one does
not sound very meaningful.
What do you have in /sys/bus/pci/slots?
