Kernel 5.16.11 r8169 ethernet module do not build

[Hatim Muhammed]

Hello everyone

I'm Hatim, I use Ubuntu 20.4.3 Kernel 5.11
I downloaded kernel 5.16.11 and installed it as follow:

make defconfig
make
sudo make modules_install

and now I can't connect to Ethernet
I tried again (make defconfig => make => sudo make modules_install)
But before make, I (make menuconfig) and set r8169 to <M>
and tried again, But no, it did not build, there's no .ko file

Actually when I (lsmod) I see nothing, NO MODULES ARE LOADED
I'm must be a fool to think things will be easy, but why r8169 driver
refused to build?

Here are some diagnostics:
