phy_sfp_probe(9)

🎀 NAME 🎀

okay so bestie, this is phy_sfp_probe(9) from the Kernel API Manual, and it is literally the probe for a SFP cage attached to this PHY device. That’s the whole vibe: SFP cage, PHY device, probe. No cap. 💅✨

✨ SYNOPSIS ✨

the signature is right here, locked in and iconic:

int phy_sfp_probe (struct phy_device *phydev );

🌸 ARGUMENTS 🌸
