Subject: [PATCH v6 0/1] vfio/qat: Add vfio_pci driver for Intel QAT SR-IOV VF device

This patch is the last one of set "crypto: qat - enable QAT GEN4 SR-IOV
VF live migration" [1].

The first 1~9 patches of this set introduce the helpers in QAT PF driver
to support the live migration of Intel QAT SR-IOV VF device and have
been merged into Herbert's tree [2].

This one adds a vfio pci extension specific for QAT which intercepts the
vfio device operations for a QAT VF to allow live migration.

Changes in v6 since v5 [1]:
- Introduce more QAT device specific information around migration in the
commit message and comments in driver (Alex)

Just a nit. :) For a single patch series, no need to have a cover-letter.
You can include the change log after the s-o-b line and prior to the file
list. Like below:
