One of the goals for Open vSwitch is to decouple kernel and userspace software, so that either one can be upgraded or rolled back independent of the other. To do this in full generality, it must be possible to add new features to the kernel vport layer without changing userspace software. The customary way to do this in the Linux networking stack is to use Netlink and in particular Netlink attributes. This commit adopts that model for the vport layer. It does not yet actually start using the Netlink socket layer, which will come later. Signed-off-by: Ben Pfaff <blp@nicira.com> Acked-by: Jesse Gross <jesse@nicira.com>
