Documentation/PCI/endpoint/pci-endpoint-cfs.rst explains how a user
has to create a directory in-order to create a 'EPF Device' that
can be configured/probed by 'EPF Driver'.

Allow user to create a sub-directory of 'EPF Device' directory for
any function specific attributes that has to be exposed to the user.

Maybe add an example sysfs path in the commit log?

Seems like there's restriction on hierarchy depth in sysfs, but I
don't remember the details.  Moved Greg to "to" in case he wants to
comment.

This is configfs, not sysfs, so I really do not know, sorry.
