Linus Torvalds1da177e2005-04-16 15:20:36 -070032 * Known bugs:
33 * We suspect that on some hardware no TX done interrupts are generated.
34 * This means recovery from netif_stop_queue only happens if the hw timer
35 * interrupt fires (100 times/second, configurable with NVREG_POLL_DEFAULT)
36 * and the timer is active in the IRQMask, or if a rx packet arrives by chance.
37 * If your hardware reliably generates tx done interrupts, then you can remove
38 * DEV_NEED_TIMERIRQ from the driver_data flags.
39 * DEV_NEED_TIMERIRQ will not harm you on sane hardware, only generating a few
40 * superfluous timer interrupts from the nic.
