device shut down question

[Stephane Dalton <sdalton@xxxxxxxxxxxxx>]

Hi,

I was looking at the acenic driver in the 2.4.3 kernel release I've seen this
comment:

*... The case to be aware of is when shutting down the device
* and cleaning up where it is necessary to make sure that
* start_xmit() is not running while this is happening. Well DaveM
* informs me that this case is already protected against ... bye bye
* Mr. Spin Lock, it was nice to know you.

Can you give me a pointer in the code where this awareness mechanism is
implemented, I've been working on an E3 driver a while ago and I had this same
concern.

Thanks
