Perhaps the enclosed patch will help. It creates a new config option
to make these optimisations for you, and if that option is enabled,
both of the above limits are quadrupled (to 64 and 16 respectively).
Other drivers would need the relevant lines adding to them as
appropriate, as I've only touched those two, but the relevant
documentation is also included.
Best wishes from Riley.
