We intend this patch to improve spidernet interrupt handling to be more strict. We had following problem and this patch solves it. -when CONFIG_DEBUG_SHIRQ=y, request_irq() calls handler(). -when spider_net_open() is called, it calls request_irq() which calls spider_net_interrupt(). -if some specific interrupt bit is set at this timing, it calls netif_rx_schedule() and spider_net_poll() is scheduled. -spider_net_open() calls netif_poll_enable() which clears the bit __LINK_STATE_RX_SCHED. -when spider_net_poll() is called, it calls netif_rx_complete() which causes BUG_ON() because __LINK_STATE_RX_SCHED is not set.
