iavf_get_channels(9)

💅 iavf_get_channels — Kernel API Manual, section 9 🎀

okay so bestie, we're in the iavf_get_channels(9) era and honestly? it's a little one. a tiny icon. she does exactly one thing and she does it cute, so let's get into it ✨

---

🌸 NAME 🌸

iavf_get_channels — literally just gets the number of channels the device can support. that's the whole job. main character energy, minimal plot 💅

---

✨ SYNOPSIS ✨

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

no return value, she just goes in there and fills stuff out. no cap 🫶

---

🦋 ARGUMENTS 🦋

• netdev — the network interface device structure, aka the whole vibe of the device itself
• ch — the channel information structure, aka the little form she fills in for you

---

💖 DESCRIPTION 💖

so for the purposes of our device, we only use combined channels — like, a tx/rx queue pair, they're glued together, that's the whole thing, we don't do solo acts 🎀

and then — plot twist — she reports one extra channel to match our "other" MSI-X vector. yes queen, one bonus channel, matching the vibe of that extra vector. it's giving "plus one" 💅
