--- Comment #2 from Murat <murat@sunnyvalley.io> ---
Hi,

It looks like this bug effects quite many FreeBSD versions. This was present in
FreeBSD 11.x and I could confirm this is present in FreeBSD 12.x

Fix looks very easy. 

Impact will be huge since em(4) driver is being used by many hypervisors (QEMU,
Proxmox, VirtualBox, VMware) and you can find this adapter oboard in many COTS
hardware. 

Most obvious effect is you cannot run netmap(4) on em VLAN interfaces.
