idpf_get_channels(9)

💅 idpf_get_channels(9) — the kernel API manual, but make it make sense ✨

okay bestie, so this is a page from the Kernel API Manual, and today's main character is idpf_get_channels — the lil function that tells you how many channels your device can actually handle 🎀

---

🌸 NAME 🌸

idpf_get_channels — literally just gets you the number of channels supported by the device 💖

---

✨ SYNOPSIS ✨

void idpf_get_channels (struct net_device *netdev , struct
ethtool_channels *ch );

no cap, that's the whole signature 🫶

---

🦋 ARGUMENTS 🦋

• netdev — the network interface device structure, aka the whole vibe of your NIC 😌
• ch — the channel information structure, where the answer gets dropped off 💌

---

👑 DESCRIPTION 👑

so what does it actually do? It reports the maximum of TX and RX 🔥

and then — plot twist — it reports one extra channel to match our MailBox Queue 💀 that's the whole bit, that's the function, she's iconic and she's done 🌈
