Here are some functions in tg3, that I would like to eventually make
available to all net drivers (and other net stack users).

/* these three netif_xxx funcs should be moved into generic net layer */
static void netif_poll_disable(struct net_device *dev)
{
while (test_and_set_bit(__LINK_STATE_RX_SCHED, &dev->state)) {
current->state = TASK_INTERRUPTIBLE;
schedule_timeout(1);
}
}
static inline void netif_poll_enable(struct net_device *dev)
{
clear_bit(__LINK_STATE_RX_SCHED, &dev->state);
}
/* same as netif_rx_complete, except that local_irq_save(flags)
* has already been issued
*/
static inline void __netif_rx_complete(struct net_device *dev)
{
if (!test_bit(__LINK_STATE_RX_SCHED, &dev->state)) BUG();
list_del(&dev->poll_list);
clear_bit(__LINK_STATE_RX_SCHED, &dev->state);
}
