Enable AES-GCM in kernel LKCF /proc/crypto for QAT in Denverton (C3000 atoms)

Currently QAT only have AES-CBC enabled for the kernel LKCF. Would it be possible to add AES-GCM support as well?
# cat /proc/crypto | grep qat

We understand modern Xeon processor have very good performance using the AESNI instruction sets. However on the Deverton C3000 SoC devices, the performance of AESNI based AES-GCM performance is still limited. We are seeing with software only the IPSec performance is only around 300-400 Mbps for AES-GCM. By using QAT through the LKCF, we can have around 1.5Gbps IPSec with AES-CBC. So we believe by enable AES-GCM in LKCF QAT driver, much better IPSec performance can be achieved.
