Hi all,
We have got a consumer desktop equipped with Realtek RTL8125 2.5GB
Ethernet [1] recently. But, there is no related driver in mainline
kernel yet. So, we can only use the vendor driver [2] and customize
it [3] right now.
Is anyone working on an upstream driver for this hardware?

At least I'm not aware of any such work. Issue with Realtek is that
they answer individual questions very quickly but company policy is
to not release any datasheets or errata documentation.
RTL8169 inherited a lot from RTL8139, so I would expect that the
r8169 driver could be a good basis for a RTL8125 mainline driver.

Meanwhile I had a look at the RTL8125 vendor driver. Most parts are
quite similar to RTL8168. However the PHY handling is quite weird.
2.5Gbps isn't covered by Clause 22, but instead of switching to
Clause 45 Realtek uses Clause 22 plus a proprietary chip register
(for controlling the 2.5Gbps mode) that doesn't seem to be accessible
via MDIO bus. This may make using phylib tricky.

In case you haven't seen it yet: Meanwhile I added RTL8125 support to
phylib and r8169, it's included in 5.4-rc1. I tested it on a
RTL8125-based PCIe add-on card, feedback from your system would be
appreciated. Note that you also need latest linux-firmware package
from Sep 23rd.

Thank you!!!
