I'm not sure what if your trouble here.

	if you want to configure global IPv6 address with arbitrary
	address prefix (upper 64bit) and/or interface identifier (lower 64bit),
	you can do this:
	(prefix = 3ffe:501:ffff::/64, interface id = 0:0:0:1)

	# ifconfig ne2 inet6 3ffe:501:ffff::1 prefixlen 64 alias

	use ifconfig.  rtsol is just like dhclient for IPv6, only useful
	when you have a router.  (NOTE: Don't run rtadvd and rtsol on the
	same node, this is not the right way!)

	ff:fe is not IPv6 thing,  this is to convert 6byte MAC address into
	8byte EUI64 address.  IEEE decided this, IIRC.
