This patch adds support for NLA_POLICY_NESTED_ARRAY() policies.
Example spec (from future wireguard.yaml):
-
name: wgpeer
attributes:
-
name: allowedips
type: indexed-array
sub-type: nest
nested-attributes: wgallowedip
yields NLA_POLICY_NESTED_ARRAY(wireguard_wgallowedip_nl_policy).
This doesn't change any currently generated code, as it isn't
used in any specs currently used for generating code.

---Is this keyed of off the sub-type? Does you mean that all the existing uses of 'sub-type: nest' don't generate code today? Or that this _attr_policy implementation is not called yet? I checked and we have quite a number of uses:
