Thanks. I think I have tried most (if not all) released kernels (from 5.10 to present day 6.1) I adopted Bullseye a few weeks before it became the stable branch. Bookworm supports the Realtek R8125 NIC which I noted this week is also using the R8169 driver with the latest Bullseye kernel. I

Thanks. That is really a disappointing response because: 1. Hardware selected based on Debian 4.x kernels in Buster that operated safely was broken by the 5.10 and above kernels in Bullseye and Bookworm 2. You ask us to report a bug if the R8168-dkms package has to be used so we did, now no

Thanks for a prompt response. We used the alpha 2 ISO release. I had checked sources.list. The two of us working on this were unaware that there was a difference between non-free-firmware and non-free. non-free-firmware is not mentioned as a component on the debian wiki
