idpf_vport_get_hsplit(9)

✨ idpf_vport_get_hsplit ✨

okay so this is a page from the Kernel API Manual (yes, the idpf_vport_get_hsplit(9) one 💅) and it's honestly so simple it's giving "one job and she does it." Basically: you hand her a virtual port, she tells you what the header split situation is looking like rn. That's it. That's the whole function 🎀

---

🌸 NAME 🌸

idpf_vport_get_hsplit — get the current header split feature state

like... she gets the hsplit state. no cap. that's the vibe 🦋

---

✨ SYNOPSIS ✨

u8 idpf_vport_get_hsplit (const struct idpf_vport *vport );

one function, one argument, returns a u8. lowkey iconic for how unbothered it is 💜

---

🫶 ARGUMENTS 🫶

• vport — the virtual port you want to query the state for. bestie, this is the one thing you gotta give her. she's not gonna guess 🔥

---

👑 RETURN 👑

she returns one of these three, and ngl you should know which is which so you don't get caught out:

• ETHTOOL_TCP_DATA_SPLIT_UNKNOWN — if it's not supported. so like, the feature isn't even a thing here 🙈
• ETHTOOL_TCP_DATA_SPLIT_DISABLED — if it's disabled. it exists, it's just not turned on 💀
• ETHTOOL_TCP_DATA_SPLIT_ENABLED — if it's active. she's up and running, main character energy ⭐

fr fr, those are the only three vibes you're getting back. no in-between, no surprises 🧚
