Please tell me immediately if there is something newer available.


I, don't have a whole newer driver, but I hope this fix isn't too late
for the ethernet driver.



It's never too late - as long as somebody maintains it.


I've found that the ethernet cannot be brought up more than once.  IE:
If the eth0 is brought down and then back up, it no longer works.  A fix
is to add:

  enable_irq(pD->irq);

just before the return in the function eth_enable.



Ah, I see - consider it applied - no need for a patch
if this was the only modification.

Thanks


Subsequent testing shows that while this works functionally, it will result in a warning message the first time the interface is brought up. That may be a small price to pay, since without this change the interface cannot be brought up a second or third... time.

To avoid this warning add a disable_irq call in the probe function - but be careful not to disable irqs each time the probe function is called, only call disable_irq after the sole successful call to the probe function!
