Author: jhb Date: Thu May 28 22:01:50 2015 New Revision: 283670 URL: https://svnweb.freebsd.org/changeset/base/283670 Log: Create a separate kobj interface for leaf-driver PCI IOV methods. Leaf drivers should not import the PCI bus interface to add IOV handling. Instead, move the IOV client methods to a separate kobj interface.
