    I touched upon this in another reply.

    For forcedeth it should never be zero, it gets set in
    netif_napi_add() to RX_WORK_PER_LOOP which is unconditionally
    defined to 64.

    Afterwards napi->weight should never be modified and that is
    what is passed into n->poll().

    Perhaps some memory scribble is causing it to be zero'd.
