Reporting SFP presence status

[Martin Hundebøll]

Hi Andrew,

I've browsed the code in drivers/net/phy, but haven't found a place 
where the SFP module status/change is reported to user-space. Is there a 
"standard" way to report insert/remove events for SFP modules, or should 
we just add a custom sysfs attribute to our driver?

Thanks,
Martin
