idpf_set_channels(9)

💅 idpf_set_channels — like, the channel count glow-up ✨

okay bestie, so this one's from the Kernel API Manual — section 9 of the manual pages, if you were wondering about that adorable (9) hanging off the name. And the name itself? idpf_set_channels. Say it with me. Iconic.

---

🌸 NAME 🌸

idpf_set_channels — set the new channel count. That's it. That's the whole vibe. She's here to change the number of channels, periodt. 💅

---

✨ SYNOPSIS ✨

int idpf_set_channels (struct net_device *netdev , struct
       ethtool_channels * ch );

Like, look at her. Two arguments, returns an int. Main character energy fr fr. 🔥

---

🎀 ARGUMENTS 🎀

• netdev — the network interface device structure. You know, the whole entire netdev. The big one. 👑
• ch — the channel information structure. This is where the channel tea lives. 🍵

---

🦋 DESCRIPTION 🦋

So what she actually does: she negotiates a new number of channels with CP. Like a whole conversation. A negotiation. Very diplomatic of her, honestly. 🫶

She returns 0 on success, and negative on failure. So if you see a negative number come back, that's your sign that it did not, in fact, slay. 😭

ngl, the whole idpf squad lives over in ./drivers/net/ethernet/intel/idpf — that's the address, bestie, write it down. 🎀

okay that's the whole page!! sourced straight from ./drivers/net/ethernet/intel/idpf, dated October 2026, and yes she's still idpf_set_channels(9) the whole way through. mwah 💋🦋💖
