Feature to know the time it takes to update OVS
ODL takes too much time to update the classification rules and we would like to measure it to use it as a proof point that it is not acceptable. This feature allows to measure it. Change-Id: I00ade7e4aee7c9c81843077104727b98ad9bfea3 Signed-off-by: Manuel Buil <manuel.buil@ericsson.com>
