Could you move this RA specific snippet over to ndisc.c?
Hmm
How do you use this option?
You use jumbo frames on the on-link network and announce all routes via route options where you also want to communicate to with jumbo frames?
I wonder if an offlink_mtu parameter would be more suitable?
Thanks, Hannes
