- Disable all interrupts in the beginning of attach. Without this, interrupt storm occurs while cold == 1 on some environment. - Disable command complete interrput for a while to prevent hangup on some enviroment. I'm sorry, I don't know what this bit is :-| - Check all status bits and return 0 if an interrupt is not for me. It's required for INTx. Tested on XEN3_DOM0 because it doesn't support MSI yet. - Return 1 when a interrupt is processed.
