From: Ursula Braun <ursula.braun@xxxxxxxxxx>
If HiperSockets Network Traffic Analyzer is switched off, but trace
disabling fails somehow, the qeth driver does not switch off its
promisc mode status. A following sniffer reactivation fails, since
qeth does not see a need to reenable tracing.
At the same time the code analyzing results of trace commands is
restructured.
