As a side question, I suppose it would be possible to put PHYs on copper
SFP modules even if they don't natively implement I2C access. In that case,
if configuration from the host is at all available, how does that happen,
is there some sort of protocol translator (I2C -> MDIO) on the module?
Do you know of any part number for an I2C controlled MDIO controller?
