2023-09-14idpf: add controlq init and reset checksJoshua Hay14-3/+1851
At the end of the probe, initialize and schedule the event workqueue. It calls the hard reset function where reset checks are done to find if the device is out of the reset. Control queue initialization and the necessary control queue support is added. Introduce function pointers for the register operations which are different between PF and VF devices.

2023-09-14idpf: add module register and probe functionalityPhani Burra5-0/+193
Add the required support to register IDPF PCI driver, as well as probe and remove call backs. Enable the PCI device and request the kernel to reserve the memory resources that will be used by the driver. Finally map the BAR0 address space.

2023-09-14virtchnl: add virtchnl version 2 opsPavan Kumar Linga2-0/+1724
Virtchnl version 1 is an interface used by the current generation of foundational NICs to negotiate the capabilities and configure the HW resources such as queues, vectors, RSS LUT, etc between the PF and VF drivers. It is not extensible to enable new features supported in the next generation of NICs/IPUs and to negotiate descriptor types, packet types and register offsets. To overcome the limitations of the existing interface, introduce the virtchnl version 2 and add the necessary opcodes, structures, definitions, and descriptor formats. The driver also learns the data queue and other register offsets to use instead of hardcoding them. The advantage of this approach is that it gives the flexibility to modify the register offsets if needed, restrict the use of certain descriptor types and negotiate the supported packet types.
