IPv6 over pfSense 802.1q VLAN limits ICMP6 data size to 1240 bytes

[ChrisJenk]

Apologies for cross posting this. I originally posted it in the IPv6 topic but I'm hoping it might get more visibility here.

Details are in https://forum.netgate.com/topic/185375/ipv6-over-pfsense-802-1q-vlan-limits-icmp6-data-size-to-1240-bytes

Thanks for any thoughts...
