52 * message to the network node. It could be a delete + add or a single

67 * the new one. The currently installed entry is derived by the Match
68 * portion of the passed Flow. FRM looks in its database for a previously
69 * installed FlowEntry which Match equals the Match of the passed Flow. If
70 * it finds it, it will request the SDN protocol plugin to replace the
71 * existing flow with the new one on the network node. If it does not find
72 * it, it will request plugin to add the new flow. If the passed entry is
73 * not valid an error code is returned. If the existing flow is equal to the
74 * passed one it will be a no op and success code is returned.
