Since 'commit f332a9d53e33 ("softirq: defer softirq processing to
ksoftirqd if CPU is busy with RT")', all softirqs are deferred
to ksoftirqd if one of the potentially long softirqs are pending.
This can significantly delay processing of tasklets and timers,
which are frequently designed to be running at high priority.
Defer only the potentially slow softirqs to ksoftirqd.

is connected to one of its downstream ports. Add support to
enable test modes on any desired downstream port of an external
hub. The port and the test mode can be selected via sysfs nodes.
