The following properties are added to the PortContext object passed to ML2 mechanism drivers for port operations: * bound_driver - name of current bound driver * original_bound_driver - name previously bound driver in an update * original_bound_segment - network segment used in previous binding Some issues with the existing ML2 port binding unit tests were also fixed. The remainder of the fix for bug 1276395, making these binding details available to mechanism drivers when a port is deleted, will be addressed as part of the fix for bug 1276391. Partial-Bug: #1276395 Change-Id: I9ecff4a4e044920ed2dde709c89aeb9bc773220d
