Can not start up QuickAssist adapter on CentOS 7

Hi Everyone,

I am testing QuickAssist for SSL usage.

I have a QuickAssist 8950 adapter and installed on Dell R630.

I followed this document for installation:

https://01.org/sites/default/files/page/330750-005_qat_gsg.pdf

I added intel_iommu=off on GRUB2 and restart the server and the QAT driver installed without error.

But when comes to systemctl start qat_service, it reported can not start up the adapter, the messages as the following:

Thanks.
