OpenBSD is different to most other systems in how it handles packet
sizes and MTU on interfaces. ...
Thank you very much for this detailed explanation.
My network college would be happy, if I could would set the MTU to 9180
and I tried to set this on aggr0 and ix* via:
ifconfig ix0 down
ifconfig ix0 mtu 9180
but I always get the error:
ifconfig: SIOCSIFMTU: Device busy
What is the procedure to set the MTU?
Kind regards
