It's found my r8169 ethernet card at hand has a device ID
of 0x0000 which wasn't on the list of rtl8169_pci_tbl. Add
a new entry to make it work:

01:00.0 Class 0200: 10ec:0000

I don't know about this.
A value of zero could mean the device is mis-responding to
PCI config space requests or something like that.

It was working fine on my retired Windows XP home PC with same devcice
ID listed, so I guess r8169 driver for windows system knows 0x0000 is
also valid.

It is also possible the device comes up in a different state.

Under windows does it show with that device ID of zero?

yup. More precisely, I checked how BIOS enumerate it by PCIe analyzer
and see it does report 0x0000 as device ID.
