     24== OpenFlow Actions in SW vs HW path on the switch ==
    2525Many of the OF switches deployed do not support the whole OF 1.0 spec in the hardware path, when an action is sent to the SW path this causes great degradation on the performance. There is no easy way to tell which actions are supported in HW and which actions are supported in SW. Below is a list of known actions that end up is software, that have been discovered after extensive debugging.
