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. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
