in some networks we are working with jumbo mtu's. If I configure the mtu to
the native interface all works fine.
ifconfig ixg1 mtu 9000 (no problem)
but
ifconfig vlan850 ip4csum tcp4csum udp4csum tcp6csum udp6csum ip4csum-tx
ip4csum-rx tcp4csum-tx tcp4csum-rx udp4csum-tx udp4csum-rx tcp6csum-tx

The attached patch should prevent the crash, does it?
Yes, the patch solves the problem. Can you commit the patch into the
netbsd-7 kernel and (if necessary) into -current.
Thank you for your efforts
