Bug#1111507: firmware-realtek-udeb missing rtl8168e-3.fw (needed for d-i)

[Andrea - <andrea.carbonaro55@gmail.com>]

Package: firmware-nonfree
Version: 20250209-1
Severity: important
Tags: d-i

Dear Maintainer,

on Debian 13 (Trixie), the package firmware-realtek-udeb does not include
the firmware file rtl8168e-3.fw, which is required by the common Realtek
RTL8168/8111 network interface.

As a result, during installation with debian-installer (both stable and
daily images), the installer stops asking for the missing firmware.  
After installation, the firmware works fine because the full package
firmware-realtek provides it.

Steps to reproduce:
1. Boot Debian Trixie installer (netinst or live with d-i).
2. Network hardware: Realtek RTL8168/8111.
3. Installer asks for rtl8168e-3.fw, which is not present in /lib/firmware.

Expected result:
firmware-realtek-udeb should provide rtl8168e-3.fw, so debian-installer
can use the NIC without manual intervention.

Thanks,
Andrea
