Hi Antoine
When is a GoP link interrupt signalled? When is a port without a PHY
actually up/down?
With SFF/SFP ports, you generally need a gpio line the fibre module
can use to indicate if it has link. Fixed-phy has such support, and
your link_change function will get called when the link changes.
And this is another bit of code you probably need to change in a while
with phylink lands.
