phy_port_update_supported(9)

💅 phy_port_update_supported(9) 💅

okay bestie, welcome to the Kernel API Manual entry for phy_port_update_supported — yes the header says phy_port_update_supported(9) twice, that's just how manpages do, we don't question it 🎀

---

✨ NAME ✨

phy_port_update_supported — sets up the port->supported field 🫶

---

🌸 SYNOPSIS 🌸

void phy_port_update_supported (struct phy_port *port );

literally that's the whole thing. no return value, no drama, no cap 💅

---

🦋 ARGUMENTS 🦋

• port — the port you're updating, bestie. that's the one. the port in question 👑

---

💖 DESCRIPTION 💖

so here's the vibe check: once the port's medium list and number of pairs have already been configured — based on firmware, straps, and vendor-specific properties — then you may call this function to update the port's supported linkmodes list. ✨

and the icon behaviour, the moment everybody needs to know: any mode that was manually set in the port's supported list remains set. 🎀 like, it stays. it's a main character, it's not getting dropped. periodt. 💀

ngl this is one of those "call it at exactly the right time or don't call it" situations — the medium list and pair count gotta be locked in first, iykyk 😭
