Hi Tom Did you see the work Russell King did for phylink? https://lwn.net/Articles/667055/ Rather than doing your own proprietary i2c infrastructure, use the standard Linux i2c infrastructure. The SFP modules are then just normal i2c devices on a normal i2c bus. The work Russell did can then access them, export them to user space, get the PHY modes correctly setup, etc. Andrew
