Overview

Overrides IOService::systemWillShutdown in order to notify network clients that the power-managed controller should be disabled. As a result, drivers can expect their disable method to be called before system shutdown or restart. This implementation is synchronous and can block before calling IOService::systemWillShutdown and return.
