This patch introduces the functionality of loading and unloading
physical function.
qedn_probe() loads the offload device PF(physical function), and
initialize the HW and the FW with the PF parameters using the
HW ops->qed_nvmetcp_ops, which are similar to other "qed_*_ops" which
are used by the qede, qedr, qedf and qedi device drivers.
qedn_remove() unloads the offload device PF, re-initialize the HW and
the FW with the PF parameters.
The struct qedn_ctx is per PF container for PF-specific attributes and
resources.

This driver module version is not used in this series and more
important the module version have no meaning in upstream at all
and the community strongly against addition of new such code.
#define QEDN_MODULE_NAME "qedn"
And the general note, it will be great if you convert your probe/remove
flows to use auxiliary bus like other drivers that cross subsystems.
Thanks
