Modify RIO enumeration to apply RX/TX enable operations only to active
switch ports. This will leave inactive ports in condition consistent with
their state.

It's unclear (to me) what the effects of this are.  Does it fix some
user-visible malfunction?  Or is it just some nice-to-have thing?  Or
what?

This patch is applicable to kernel versions starting from v2.6.35.

Is that a recommendation that such a backport be performed?  If so,
please provide the reasoning.
