SR-IOV capabilities not detecting for INTEL QAT Crypto PCI device

[rajesh_kumar_a_]

I am using Intel Corporation Atom processor C2000 chip based linux machine. Loaded with ubuntu with kernel 4.4.x version. from lspci i could see SR-IOV (single root I/O virtualization) capability has been detected for Ethernet ports but not for QAT PCI.

no SR-IOV capability displayed.

tried multiple options on grub file, BIOS settings (nothing displayed for Virtualization).
Badly need help on how to get this capability for the QAT chip, please provide whether anything i need to in grub file, BIOS settings or any drivers required for the same?. 
Stuck my testing work because of this issue.
