Jumbo frames crash
After enabling or disabling mtu 9000 on lagg0 and both interfaces in the lagg, freenas will reboot.

Yes. Specifying 'mtu 9000' as an option on each interface and the lagg works fine. Confirmed 9k packets being sent and received on the wire, no reboot. Previously had issues of random reboots while option enabled, not sure if this is involved with the 9k mtu or not. Had turned off mtu 9000 for 3 weeks with no reboot for this duration, turned back on on the 23rd. I am going to leave this option on permanently now and will include any debug/crash logs I can going forward if present.
