BT Homehub 5A Hardware crypto support

The datasheet from Lantiq for the chipset used in the HH5A says there's a hardware "Data Encryption Unit for IPSec".

Looking on my HH5A running 17.01.1, I don't see /dev/crypto so I assume that 17.01.1 doesn't actually support this hardware crypto accelerator.

What are the chances that support for this will be added in the near future?
