Firmware file has been submitted by Realtek, however it may take time until
the next linux-firmware release is published. In the meantime you can get the
firmware file from here:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/rtl_nic/rtl8125d-1.fw
Just place it under /lib/firmware/rtl_nic/
