I'm testing both. I thought I might have some throughout issues with the virtio
driver
and switched to the e1000 for testing. Unfortunately the e1000 driver leads to
openbsd
kernel panics > 200 Mbit/s so I switched back to the virtio driver which is
more stable.
The "error: recvfrom xxx failed: Host is down" problem is unaffected by
whichever NIC
driver I use.
