This set includes fixes to the PFVF logic but also refactoring in
preparation for updates to the protocol and support for QAT GEN4
devices.
The main changes introduced by this set are:
* A fix for a bug introduced in the previous PFVF set related to an
undetected timeout;
* The refactoring and rework of the PFVF message handling logic which
includes changes to the ACK behaviour;
* The introduction of adf_pfvf_gen2.c which includes logic common
to QAT GEN 2 devices;
* The introduction of the pfvf_ops structure to isolate PFVF related
code inside the adf_hw_device_data structure and facilitate the
introduction of PFVF for QAT GEN4;
* The reorganization of the PFVF code structure so that message logic
is separated from low level communication primitives and the protocol.
Changes since v1:
- Fixed compilation error with CONFIG_PCI_IOV=n, reported by kernel test
robot <lkp@xxxxxxxxx>;
Changes since v2:
- Added patch to fix a NULL pointer dereference in case of a spurious
interrupt with QAT GEN4 devices. This was due to a missing function;
- Minor style changes.
