Subject: [PATCH] Use dev_port for the ID of a network device.

For network devices on the same PCI function, dev_id should not be used,
since its purpose is for IPv6 support on interfaces with the same MAC
address.

The new dev_port sysfs attribute should be used when it is found. When
it is not, using dev_id might work.
