A board reseller isn't required to have an ID, only the people making
the PCI chips. A PCI device must have an ID, and may optionally have a
The board vendor typically programs the subsystem ID with their own
values, although a few chips allow the configuration EEPROM to also
override the chip's standard PCI ID. The motivation to do this is to
appear to have a unique product, for instance when the vendor doesn't
want the customer to know that "$80 value" NIC is exactly the same a $6
generic rtl8139 board.
Actually, the vendor ID is more general than just PCI devices. Many
other devices (e.g. USB) now use a 16+16 bit Vendor/Device ID. Much
like the 2+22+24 bit IEEE station address, this kind of standardization
is a very good thing.

No. The list that Linux uses was apparently user-submitted guesses.
And once there is an entry, it is never validated.

The 1385:511a is the subsystem ID for the Netgear FA511, which should
always use the 1317:1985 ADMtek Comet/Centaur chip.
This is similar to the 1385:f311 (subsystem ID) Netgear FA311 v1 board,
which always uses the 100B:0020 (primary ID) National Semiconductor
