Subject: [PATCH] udev/net_id: parse _SUN ACPI index as a signed integer
Negative value means there is no match between a PCI device and any of
the slots. In the following commit we will extend this and value of 0
will indicate that there is a match between some slot and PCI device,
but that device is a PCI bridge.
(cherry picked from commit 3e545ae5abcf258791eacbee60c829c100a33274)
