bleah, i still don't like how this reads, but i'm not sure how to
do this syntax otherwise.

you should be able to treat the ccc option as yet another layer of
encapsulation;

	option space ccc code width 2 length width 2;
	option ccc.first code 1 = ip-address;
	option ccc.second code 2 = ip-address;

	option docsis.ccc code 2170 = encapsulate ccc;

	option ccc.first 1.1.1.1;
	option ccc.second 2.2.2.2;

vsio->docsis is only one layer of indirection, it's possible there is
a bug when there are more than one layer.  it's supposed to work, but
we've found quite a few corner cases already testing configs like
these...
