i have read this post and he wrote, that he has edit the "initramfs" but when i search this file, i didn't found anything. That is the reasen why i ask. And the only answer i get "look here and read" ans when i look and read, i didn't found any solution.

Of course he edited initramfs, that's what his PR does but now you don't have to as this PR has been merged.

I guess you missed the next part where he mentions adding the wol_* parameters to the kernel command line (which in the case of the Pi is in cmdline.txt) to activate the WOL functionality.

Honestly, it's all there for you - first comment. Read it. I don't want to be an arse about this, but there's no point me or anyone else reproducing details that have already been adequately described elsewhere and where you've been told to look.
