Detection of this chip version was removed in May last year and this is
the first such report. So it doesn't seem there's a significant number
of these old cards out there. It was the first PCIe version, and it's
broken in different ways, requiring version-specific workarounds.
I'd prefer not to re-add these workarounds in mainline, also given that
cards with modern versions like RTL8168h are available new for <10€.
Alternatively you can build a custom kernel, or use r8168 vendor driver.
