On a "true" P-to-P link, there is no netmask, no? A netmask is a concept that applies to broadcast media, like Ethernet. Even if you only have two hosts on an Ethernet link, it's not really P-to-P in the strict sense.
An interface needs a prefix length (subnet mask for those of us stuck in the '90s) so the system knows which addresses are directly connected through the interface in question. Whether the link is point- to-point, broadcast or NBMA doesn't matter for that purpose.
But as for how ND works over a P-to-P, the FreeBSD stack seems to be a little odd.

But despite all of that, it all works pretty sweetly.
There have been compatibility issues with PPP for IPv6 in the past because some implementations would do ND and others wouldn't...
