This is the PF, not the VF.

I reckon that your issue is that you are trying to use the PF (not 
supported by DPDK)
instead of the VF.

 From 
http://dpdk.readthedocs.io/en/v2.2.0/cryptodevs/qat.html#installation-using-01-org-qat-driver:

"You can use|cat/proc/icp_dh895xcc_dev0/version|to confirm the driver is 
correctly installed.
You can use|lspci-d:443|to confirm the bdf of the 32 VF devices are 
available per|DH895xCC|device."

You should pass-through one of the VFs.
