You can still buy them new at Newegg for goodness sakes!the point that it's only used virtualized, since PCI (not PCIE) have been long dead.
My point is precisely the opposite. It is a real device, it exists in real systems and it is used in those systems. I worked on embedded systems that ran Linux and used e1000 devices. I am sure they are still out there because customers are still paying for support of those systems.
Yes, PCI(-X) is absent from any current hardware and has been for some years now, but there is an installed base that continues. What part of that installed base updates software? I don't know, but I would not just assume that it is 0. I know that I updated the kernel on those embedded systems that I worked on when I was supporting them. Never at the bleeding edge, but generally hopping from one LTS kernel to another as needed.
The day is coming when all the motherboards with PCI(-X) will be gone, but I think it is still at least a few years off.
