Yes. Just looking at the layering may not reveal all details;
even at L2 we have both the selection of a particular access
device, the selection of which access operator's network to
use to begin with, and the selection of various things for
the access control part. At L3 we may or may not have something
to select, depending on scenario and whether some of the
lower-level selections already determine what we will
get at L2.

I like the handoff candidate selection term. But this may
not be the only thing that L2 does.
