💅 cfg80211_register_netdevice(9) — Kernel API Manual ✨

okay so bestie, welcome to the Kernel API Manual page for cfg80211_register_netdevice(9) — this one is lowkey important if you're doing netdev registration in wireless land 🦋

🌸 NAME 🌸

cfg80211_register_netdevice — register the given netdev 💖

✨ SYNOPSIS ✨

int cfg80211_register_netdevice (struct net_device *dev );

🎀 ARGUMENTS 🎀

  • dev — the netdev to register 👑

💅 NOTE 💅

In contexts coming from cfg80211 callbacks, you must call this rather than register_netdevice — and unregister_netdev is impossible as the RTNL is held 😭

Otherwise, both register_netdevice and register_netdev are usable instead as well. fr fr, context matters here 🫶

🧚 CONTEXT 🧚

Requires the RTNL and wiphy mutex to be held 🔒✨

⭐ RETURN ⭐

0 on success. Non-zero on error 💀

🌈 SEE ALSO 🌈

okay bestie, this is the part where the manpage pulls out its entire contact list. like, the whole group chat. every single one of these is a real page you can go read, and no i'm not skipping any of them, we're doing the full roll call 💅

🌸 that's a wrap on cfg80211_register_netdevice(9)! this lil beauty comes from ./include/net, dated October 2026, and it's filed under its own very cute little version tag, cfg80211_register_netdevice(9). go forth and register those netdevices, bestie — slay responsibly ✨🎀🦋
