Hi Andrew,

It is always possible ;). The irq status registers gets reset on read.

In such case, ack_interrupt() and did_interrupt() would be more or less the same
function, except for the returned value, I guess ?

The phy being internal, I think it is unlikely to ever share its interrupt
though. If you prefer I implement this callback, I can certainly re-spin with it
?

Thanks for the lightning fast review by the way !
