| Doc Text: |
The XFRM_SUB_POLICY feature causes all bundles to be at the finest
granularity possible. As a result of the data structure used to implement
this, the system performance would drop considerably. This update disables
a part of XFRM_SUB_POLICY, eliminating the poor performance at the cost of
sub-IP address selection granularity in the policy.
