--- Comment #20 from VinÃcius Zavam <egyp...@freebsd.org> ---
I did see it happening in HEAD (r355121/amd64) during a silly test I was
conducting trying to reproduce bug #239240. should we reopen this issue?
used components to reproduce it;
- physical hardware
(https://www.dell.com/en-us/work/shop/povw/poweredge-r440);
- intel i350 gigabit network card [igb] (class=0x020000 rev=0x01 hdr=0x00
vendor=0x8086 device=0x1521 subvendor=0x8086 subdevice=0x0002);
- live image
(https://download.freebsd.org/ftp/snapshots/amd64/amd64/ISO-IMAGES/13.0/FreeBSD-13.0-CURRENT-amd64-20191127-r355121-mini-memstick.img).
how to reproduce;
- leave NO ethernet cables plugged to the net. card's ports;
- boot the live image, and choose 'live cd' option (log in as root, of
course);
- perform an `ifconfig` to get actual status/options of all igb interfaces;
- plug a cable to the igb interface of your choice (the other end must be
connected to a switch or anything that can trigger layer1 activity);
- perform an `ifconfig` to get actual status/options of all igb interfaces;
- unplug the cable;
- perform an `ifconfig` to get actual status/options of all igb interfaces.
NOTE: after performing an `ifconfig igb0 up` and testing it all again, the
feedback to its physical status are all fine.
* igb0 is the only one showing 'WOL_MAGIC' but that's maybe some setting from
the BIOS I should check in a few.

MORE ABOUT IT: the odd situation is that we can see "status:" on all intel
interfaces even before performing the very first `ifconfig igb0 up` --- for the
onboard broadcom interfaces, there's no such a thing (all broadcom stay DOWN
and display no "status:" line before performing `ifconfig bge0 up`)
