    In the current implementation, on interface down we disabled NAPI and
    then manually drained any remaining ingress frames. This could lead
    to a situation when, under heavy traffic, the data availability
    notification for some of the channels would not get rearmed correctly.
    Change the implementation such that we let all remaining ingress frames
    be processed as usual and only disable NAPI once the hardware queues
    are empty.
    We also add a wait on the Tx side, to allow hardware time to process
    all in-flight Tx frames before issueing the disable command.
