Re: em0 WOL not working in 15.1 (82579LM)

Ok. I will make a PR.

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=296675

Yes, it runs ZFS+BE, so I can easily shove 14.x on it. Apart from it being in a closet so it takes some effort to push the power-button, but that will be solved when WOL is working again. 😂

Regards,
Ronald.
