We have Hyper-V on Windows server 2012 R2, where was deployed several hosts
with FreeBSD. That is used as the gateway, VPN server, web server, and othe=
r.
We don't use the legacy network adapter.
On all machines with a certain periodicity  network interfaces are stopping
with error "no buffer space are available".
Helps only ifconfig down/up.
