--- Comment #9 from John Baldwin <jhb at FreeBSD.org> ---
Ah, the "em0 que" thread is a separate helper thread created by the em driver
to service a taskqueue.  It is not an interrupt thread so it is not affected by
'cpuset -x'.  However, you can use 'procstat -t 0' to determine the thread ID
of that thread and bind that specific thread to CPU 3 using 'cpuset -l 3 -t
<tid>'.
