Careful, in my experience many PHYs that do have interrupt
support have buggy implementations to the point where the
interrupt support cannot be used at all.

Typically the problem is that events aren't reported reliably.

So I just wanted you to keep in mind that a chip having
interrupt support doesn't automatically mean it can be used.
