Each protocol 'registers' for I/O per interface and vif and gets assigned one object (per interface and vif) of this class.
| IoLink (FeaDataPlaneManager& fea_data_plane_manager, const IfTree& iftree,
const string& if_name, const string& vif_name,
uint16_t ether_type, const string& filter_program)
| IoLink |
Constructor for link-level access for a given interface and vif.
Parameters:
