There is history here.

In Linux, PHY has meant Ethernet PHY for a few decades. But then
SERDES came along which has a completely different sort of PHY as
well. So things like PCIe, USB, SATA, and MAC chips using speeds >
1Gbps all can make use of Generic PHYs for their SERDES.

So you need to be careful with wording, are we talking about PHYs or
Generic PHYs.
