// The following are the the operational states for WAN and LAN interfaces. //
// The order of the states seems weird, but is done for a purpose. All      //
// states >= CONNECTED can transmit data right away. States >= DISCONNECTED //
// can tx data but some set up might be needed. States < DISCONNECTED can   //
// not transmit data.                                                       //
// A card is marked UNREACHABLE if DIM calls InterfaceUnreachable for       //
// reasons other than failure to connect.                                   //

// NON_OPERATIONAL -- Valid for LAN Interfaces. Means the card is not       //
//                      working or not plugged in or has no address.        //
// UNREACHABLE     -- Valid for WAN Interfaces. Means the remote site is    //
//                      not reachable at this time.                         //
// DISCONNECTED    -- Valid for WAN Interfaces. Means the remote site is    //
//                      not connected at this time.                         //
// CONNECTING      -- Valid for WAN Interfaces. Means a connection attempt  //
//                      has been initiated to the remote site.              //
// CONNECTED       -- Valid for WAN Interfaces. Means the remote site is    //
//                      connected.                                          //
// OPERATIONAL     -- Valid for LAN Interfaces. Means the card is plugged   //
//                      in and working.                                     //
