For genuine RollBall modules (e.g. FLYPRO SFP-10GT-CS-30M with Aquantia
AQR113C) the probe now runs after initialization is complete and
correctly returns 0, so PHY detection proceeds normally.  
The FLPRO SFP module still fails to detect the PHY. It is necessary to
increase `module_t_wait` to 20 seconds. Most likely, during this time
the module loads the PHY firmware from SPI memory or from the
microcontroller (rollball bridge) via MDIO. Same probably applies to
most SFP modules with a PHY that load firmware at start-up (AQR113,
RTL8261C etc.).
Just to clarify is FLPRO a typo or a knock off ?
Do you want something to be changed here or you're just flagging that
more follow ups are needed if we want to cover more modules?
