How does this work if the driver has no interrupt support? What is the
hardware setup this has been tested with?

Hi Russell

We already know from previous patches that the Intel hardware is broken,
and does not actually deliver the interrupt which caused the wake up. So i
assume this just continues on with the same broken hardware, but they have
a different PHY connected.

Hi Russell & Andrew,

This is tested on Intel Elkhart Lake (EHL) board. We are using polling mode.
Both WoL interrupt and link change interrupt are the same pin which is
routed to PMC. PMC will wake up the system when there is WoL event.

Is the PMC also an interrupt controller?
