I was surprised that on 12.1-RELEASE there is not, by default, wake on
lan for the ethernet drivers. As I browse internet and many forums, it
appears that I have to add a patch (my ethernet is bge) to the driver,
but it seems that this patch is only "almost working".
Anybody has a same problem ? Any working patch ? Solutions ?

Why would it be a default?  Who wakes-on-LAN servers?   Or even
desktops?

WoL requires telling the card to stay on to receive the magic packet
after shut down time (simplified explanation anyway).

How to get the card to do that will be different between vendors and
their product lines, hence it is driver specific.

I have a similar issue with my system which has NICs using the igb
driver (last time I checked).

Hum. I came from the Linux world where this thing is "by default".
I've never had to patch a lan driver. So I'm suprised that I have to
make specific things w/ FreeBSD. (Warning: No troll intended !!).

And I'am ready to patch my gbe (Broadcom I think) driver if someone
tell me where I can find one..

WRT it being required to patch it.. That is not great but
realistically it's just due to a lack of developer time because it's a
relatively unused feature.
It also looks like the patch has caveats so people are reluctant to
commit it since it doesn't work fully.
