Get Wake-On-Lan to work

Hello!
I am trying to get Wake-On-Lan to work on my setup:
Dual boot of LibreELEC 7.0.3 and Ubuntu 16.04
In Ubuntu I am using the standard kernel version 4.4.0 and to get Wake-On-Lan to work I had to recompile a patched version of the alx driver and load it with dkms as shown in this bugreport (comments #40 and #55). Now it is working as a charm (only in Ubuntu though).
In LibreELEC it is not working out of the box as showed by this command output (there is no Supports Wake-on line)

KODINO:~ # ethtool eth0
Settings for eth0:
Supported ports: [ TP ]
Supported link modes:   10baseT/Half 10baseT/Full

Advertised auto-negotiation: Yes

MDI-X: Unknown
Current message level: 0x000060e4 (24804)
      link ifup rx_err tx_err hw wol

What I am asking is if I need to recompile the module also for LibreELEC (and in case which one and how?) or if there is some other way to get WOL to work.
Thank you a lot in advance for any help!

I went ahead and I am trying to patch the kernel with this patch: Enable ALX WoL for/since 4.9.
Here what I have done:

• I can compile and install the devel version (without my patch) successfully.

• If I take (from the build folder) the files to be patched, copy them on the Desktop and apply the patch it applies correctly.

• Then I copied the patch file in the packages/linux/patches folder

• I gave once again the command
  
  Code

  PROJECT=Generic ARCH=x86_64 make image

• It compiled correctly but still no WOL support as if the patch wasn't applied during compiling.

Maybe I am putting the patch in the wrong folder or the patch is in the wrong format ... could you tell?
Thanks

Ok I got it to work. I only had to place the patch file in the project/Generic/patches/linux directory. Hope to save someone's hours of time with this hint.
I know that this project is still young and the forum is not so much frequented, so I imagine this is the reason for the "silence" in this thread ...

Quote from mglae

The build system is surprisingly pedantic in patch file naming in some cases. For the main kernel patch directory the mask is linux-*.patch

Thank you for the hint. Infact I was already suspecting that and I renamed the patch file accordingly.

Here the script that I used to compile (successfully) the system. Maybe it will be useful to someone.
