    net: thunderx: Fix receive packet stats
    
    Counting rx packets for every CQE_RX in CQ irq handler is incorrect.
    Synchronization is missing when multiple queues are receiving packets
    simultaneously. Like transmit packet stats use HW stats here.
    
    Also removed unused 'cqe_type' parameter in nicvf_rcv_pkt_handler().

    net: thunderx: Fix for HW TSO not enabled for secondary qsets
    
    For secondary Qsets 'hw_tso' is not getting set as probe() returns
    much earlier. Fixed it by moving silicon revision check.

    net: thunderx: Fix for multiqset not configured upon interface toggle
    
    When a interface is assigned morethan 8 queues and the logical interface
    is toggled i.e down & up, additional queues or qsets are not initialized
    as secondary qset count is being set to zero while tearing down.
