💖 ice_sf_eth_activate(9) — the Kernel API Manual, bestie edition 💖

okay so picture this: you're deep in the kernel API manual (the ice one, from ./drivers/net/ethernet/intel/ice, no big deal) and you land on ice_sf_eth_activate. yes that's the whole vibe of this page. let's get into it 🫶

---

✨ NAME ✨

ice_sf_eth_activate — activate the Ethernet subfunction port. that's it, that's the job, and she does it iconically 💅

---

🌸 SYNOPSIS 🌸

int ice_sf_eth_activate (struct ice_dynamic_port *dyn_port , struct
       netlink_ext_ack *extack );

literally just hand her a dyn_port and an extack and she returns an int. the way that signature just works 😭✨

---

🦋 ARGUMENTS 🦋

• dyn_port — the dynamic port instance for this subfunction. she's the main character of this whole operation, ngl 👑
• extack — the extack, there for reporting error messages. your little messenger bestie when things go sideways 🎀

---

💜 DESCRIPTION 💜

so what is she actually doing? she activates the dynamic port as an Ethernet subfunction ✨ setup the netdev resources associated with it, and initialize the auxiliary device. that's the whole glow-up routine, start to finish 💖

no cap, she handles both halves: the netdev resource setup and the auxiliary device init. two jobs, one function call, absolute queen behavior 👑

---

🔥 RETURN 🔥

zero on success, or an error code on failure. so like — 0 means slay ✅, anything else means something went wiggy and you should go read the error 😭
