--- Comment #2 from Stephen Hurd <shurd@FreeBSD.org> ---
This will only pin the interrupt itself to the CPU, it won't change the
affinity of the taskq which does the bulk of the processing.  With iflib, t=
he
interrupt handler only schedules the task, so no real processing is done in=
 the
interrupt context.

There is an open TODO item to enable dynamically setting gtaskq affinity for
each queue, but the work hasn't been started yet.
