test program to reproduce

This program works on 10-STABLE, but on 11-CURRENT it triggers the panic.
To reproduce you need ethernet interface with enabled IPv6 and MTU less that

em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
    ether 00:22:4d:6a:5e:b9
    inet6 fe80::222:4dff:fe6a:5eb9%em0 prefixlen 64 scopeid 0x1 
    media: Ethernet autoselect (1000baseT <full-duplex>)
    status: active

% ./test fe80::1%em0
