HP 1920 Link Aggregation trunk hash policy

$

I'm configuring a bonded interface on my HP 1920 48port JG928A and I have it working, but would like to change the way it does the load balancing.

On my server (Debian 8 Jessie) I have setup both of my NICs in a bond and set the xmit_hash_policy to layer2+3 which means it should take into account the MAC and IP address when working out the hash to determine which packet goes on which ethernet device. This is not working. I can see that it's correctly set on the Debian box and I cannot find where in the HP 1920 this setting is kept.

Here is my Aggregation on the HP 1920;

interface Bridge-Aggregation1

  link-aggregation mode dynamic

  port link-type trunk

  port trunk permit vlan 1

Does the HP 1920 allow you to change the hash policy ?

What option do I put in here to set the hash prolicy to layer2+3 which will match the settings I have in debian as described in https://www.kernel.org/doc/Documentation/networking/bonding.txt under xmit_hash_policy?

UPDATE

 I looks like HP call the feature trunk-load-balance and it's settings are L2, L3 or L4. Is this feature available on the HP 1920?
