Subject: Debian Bookworm requires r8168-dkms for RTL8111D - regression from
 Buster 10.13.0

I am sending this email because of the suggestion in
/usr/share/doc/r8168-dkms/README.Debian.

Installation using a Debian Bookworm 12.2.0 amd64 DVD-ROM does not
find the onboard gigabit ethernet (RTL8111D-based) on one of my
mainboards (Gigabyte GA-890GPA-UD3H).  The network came up fine as
soon as I used apt-offline to update/upgrade, then to fetch and
install r8168-dkms.

Installation using a Debian Bullseye 11.8.0 amd64 DVD-ROM does not
find the onboard NIC either.  However, installation using a Debian
Buster 10.13.0 amd64 DVD-ROM does find the onboard NIC and can use it
directly.  (Unfortunately, installing from that DVD-ROM later failed
for some other reason.)

With r8168-dkms in operation, the relevant part of "lspci -v -v -v" reads:

Please let me know if there is further information I can provide that
would assist you in getting this supported directly by the r8169
driver.
