Current issues with Flow API: * OVS calls offloading functions regardless of successful flow API initialization. (ex. on init_flow_api failure) * Static initilaization of Flow API for a netdev_class forbids having different offloading types for different instances of netdev with the same netdev_class. (ex. different vports in 'system' and 'netdev' datapaths at the same time) Solution: * Move Flow API from the netdev_class to netdev instance. * Make Flow API dynamic, i.e. probe the APIs and choose the suitable one. Side effects: * Flow API providers localized as possible in their modules. * Now we have an ability to make runtime checks. For example, we could check if particular device supports features we need, like if dpdk device supports RSS+MARK action.
