[igb] wake on lan not working with Intel I210 for FreeBSD-12.0?

[Nikita Druba]

Hi to all!

After updating my server to 12.0-RELENG "wake on lan" function stopped 
working in my configuration. It was in April. I tried fresh kernel 
sources from 12.0-RELENG, but no result.
I have Intel I210 Gigabit Network Connection, driver igb.

rc.conf at server that I use for waking up:

ifconfig_igb0="-wol_ucast -wol_mcast wol_magic"

powered on at another server by:

wake igb0 11:22:33:44:55:66;

I tried to change sysctl by
dev.igb.0.wake=0 -> 1
but no result.

Its very important function for my backup scheme. Can anybody confirm 
this bug? May be I'm wrong, then what can I do to fix "wake up" 
function? Because all, that I found not working.

Thanx in advance.
