Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 31 | * Known bugs: |
| 32 | * We suspect that on some hardware no TX done interrupts are generated. |
| 33 | * This means recovery from netif_stop_queue only happens if the hw timer |
| 34 | * interrupt fires (100 times/second, configurable with NVREG_POLL_DEFAULT) |
| 35 | * and the timer is active in the IRQMask, or if a rx packet arrives by chance. |
| 36 | * If your hardware reliably generates tx done interrupts, then you can remove |
| 37 | * DEV_NEED_TIMERIRQ from the driver_data flags. |
| 38 | * DEV_NEED_TIMERIRQ will not harm you on sane hardware, only generating a few |
| 39 | * superfluous timer interrupts from the nic. |
