      7  * The l3uc test checks TDM and L3 unicast functionality and performance by
      8  * streaming IPv4 packets on all ports at maximum rate. All ports are
      9  * configured in MAC loopback mode and each port is paired with a same speed
     10  * port. The test calculates the number of packets needed to saturate the ports
     11  * and send the IPv4 packets from the CPU to each port pairs initially.
     12  * Then the packets are L3 switched between the port pairs indefinitely. The
     13  * MAC DA, MAC SA, and VLAN are changed every time a packet is L3 switched. Once
     14  * the traffic reaches steady state, rate calculation is done by dividing the
     15  * transmit packet count changes and transmit byte count changes over a
     16  * programmable interval. The rates are checked against expected rates based on
     17  * port configuration and oversubscription ratio. Finally, packet integrity
     18  * check is achieved by redirecting the packets back to the CPU and compared
     19  * against expected packets.
     20  *
     21  * Configuration parameters passed from CLI:
     22  * PktSize: Packet size in bytes. Set to 0 for worst case packet sizes on all
     23  *          ports (145B for ENET, 76B for HG2). Set to 1 for random packet sizes
     24  * FloodCnt: Number of packets in each swill. Setting this to 0 will let the
     25  *           test calculate the number of packets that can be sent to achieve
     26  *           a lossless swirl at full rate. Set to 0 by default.
     27  * RateCalcInt: Interval in seconds over which rate is to be calculated
     28  * TolLr: Rate tolerance percentage for linerate ports (1% by default).
     29  * TolOv: Rate tolerance percentage for oversubscribed ports (3% by default).
     30  * ChkPktInteg: Set to 0 to disable packet integrity checks, 1 to enable
     31                 (default).
     32  * MaxNumCells: Max number of cells for random packet sizes. Default = 4. Set
     33  *              to 0 for random.
     34  * TrafficLoad: Percentage of traffic load are allowed to pass through based on
     35  * port speed.
     36  * VfpEnable: Enable Vfp and fill it with miss entries.
     37  * EfpEnable: Enable Efp and fill it with miss entries.
     38  * VfpMatch: Program a hit entry in Vfp.
     39  * EfpMatch: Program a hit entry in Efp.
     40  * L3EcmpEnable: Enable ecmp for l3 routing.
