realtek.ko should be added to netboot initramfs

I believe this issue, while related, is different from #11344 (closed).

I try to boot Alpine using PXE. I am using vmlinuz-lts, initramfs-lts, and modloop-lts from latest-stable/releases/x86_64/netboot/. Boot fails with same diagnostics:

realtek.ko not loaded, maybe it needs to be added to initramfs?

Problem is that initramfs-lts has only r8169.ko, realtek.ko is located in modloop, which is loaded from network using HTTP.

This is pretty usual setup for PXE boot, so I think realtek.ko should be moved to netboot initramfs.

P.S: PXE setup is proven by years and boots fine on different hardware now.

EDIT: v3.11 and v3.12 are affected. v3.10 is not affected by this.
