IPv6 host routes on Trident I chipset

We have some older Dell S4810 switches witch Cumulus Linux 2.5.11, and we use these as route reflectors in an OpenStack installation with the calico network plugin. This has served us well, until we implemented IPv6. The plugin will create a host route (/128 prefix) for every instance created. Soon this turned out to be a problem:

# cl-resource-query
[..]
IPv4/IPv6 entries:        388,   2% of maximum value  16284
Long IPv6 entries:        256, 100% of maximum value    256
[..]

Is there any way to either install these routes into the "IPv4/IPv6 entries" table, or reallocate table space to the "Long IPv6 entries" table?
