Re: de2104x: interrupts before interrupt handler is registered

You don't bother to read. The reported interrupt is WRONG, INVALID,
INCORRECT, BROKEN, until __after__ the device is enabled. That means
that one CANNOT put an interrupt handler in place before the
device is enabled.

And my point is, even if you COULD put an interrupt handler into place before enabling the device, if the device can be in an unstable state such that the interrupt can't be acknowledged reliably, how can you handle it without causing an interrupt storm?
