Hello :)

I suspect this issue is caused by suricata for me running in IPS mode. I don't
know the exact command line used but will look into it - and run your code as
well - when I will have some more time.

The background is that this is a Fujitsu Futro S900 thin client running
Opnsense - which is based on HardenedBSD, being close to vanilla FreeBSD in
this issue, but(?) supposedly using the latest official Realtek driver - I
don't know exactly which re0 driver FreeBSD is using at the moment. The
integrated re0 nic (RTL8111E according to dmidecode) is connected to the ISP's
cable modem at a 100Mbps full-duplex connection. The upline connection is
10/2Mbps, I get the kring errors when downloading at full-speed.

Thanks for looking into this!
Cheers,
Istvan
