|
|
* 0.55: 22 Mar 2006: Add flow control (pause frame).
|
|
* 0.56: 22 Mar 2006: Additional ethtool config and moduleparam support.
|
|
* 0.57: 14 May 2006: Mac address set in probe/remove and order corrections.
|
|
*
|
|
* Known bugs:
|
|
* We suspect that on some hardware no TX done interrupts are generated.
|
|
* This means recovery from netif_stop_queue only happens if the hw timer
|
|
* interrupt fires (100 times/second, configurable with NVREG_POLL_DEFAULT)
|
|
* and the timer is active in the IRQMask, or if a rx packet arrives by chance.
|
|
* If your hardware reliably generates tx done interrupts, then you can remove
|
|
* DEV_NEED_TIMERIRQ from the driver_data flags.
|
|
* DEV_NEED_TIMERIRQ will not harm you on sane hardware, only generating a few
|
|
* superfluous timer interrupts from the nic.
