📦 version 7.3.1, in nixpkgs unstable

✨ cfg80211_check_combinations ✨

ok so this is a page from the Kernel API Manual (the cfg80211_check_combinations(9) one, iykyk) and honestly it's a short lil baddie but she's important 💅

🎀 NAME 🎀

cfg80211_check_combinations — check interface combinations

like, the whole vibe of this function is "are these interfaces allowed to hang out together" 🫶

🌸 SYNOPSIS 🌸

int cfg80211_check_combinations (struct wiphy *wiphy , struct
iface_combination_params *params );

🦋 ARGUMENTS 🦋

  • wiphy — the wiphy 💖 (yes bestie, the wiphy, that's the whole description, she's mysterious like that)
  • params — the interface combinations parameter 🌈

💫 DESCRIPTION 💫

okay so here's the tea ☕ — this function can be called by the driver to check whether a combination of interfaces and their types are allowed according to the interface combinations. that's it, that's the whole job. she's the vibe check for your interface combos ✨

⭐ RETURN ⭐

  • 0 if combinations are allowed 👑 (slay, green light)
  • Non-zero on error 💀 (not allowed, no cap)

✨ SEE ALSO ✨

Okay bestie, this is the part where the page goes "here's literally everyone else in the family" 💖 — like a group photo of the entire cfg80211/mac80211 extended universe. Every single one of these is a (9) reference, so you can just keep tapping through them like a wiki rabbit hole. No skips, no "you get the idea" — we're listing all of them 🫶

The kernel-file headliner + the foundational gang 🎀

Actions and configuration 🛠️ — this is the big one, the whole "things you can make a wiphy do" saga
