💅 ieee80211_txq_airtime_check — the kernel API manual, bestie edition ✨

okay so real talk: this is a page from the Kernel API Manual, and bestie, it's about one (1) very specific little vibe check for your WiFi driver. It's called ieee80211_txq_airtime_check</p> and honestly? She's small but she's important.

🌸 NAME 🌸

ieee80211_txq_airtime_check — check if a txq can send frame to device

Like, literally just a ✨ vibe check ✨ for your transmit queue. Is there airtime budget left? Yes or no. That's it. That's the whole function. 🎀

🦋 SYNOPSIS 🦋

bool ieee80211_txq_airtime_check (struct ieee80211_hw *hw , struct
       ieee80211_txq *txq );

Look at her. Two pointers in, one bool out. Iconic, unproblematic, lowkey perfect. 💜

💖 ARGUMENTS 💖

  • hw — pointer obtained from ieee80211_alloc_hw. Yeah, the hardware one. You know her. 👑
  • txq — pointer obtained from station or virtual interface. She's the transmit queue you're asking about, and no, you cannot just make one up. 🙈

⭐ RETURN ⭐

So here's the tea, and it's genuinely useful so pay attention please:

Returns true if the AQL's airtime limit has not been reached and the txq can continue to send more packets to the device. Otherwise it returns false. 💀

That's the whole deal. true = go off, send more. false = bestie, put the packets down, you've hit the limit. No cap. 🔥

🌈 SEE ALSO 🌈

okay this section is long — like, unreasonably long, it's giving "the entire header file got dumped into one list" energy. But I promised to keep every single one, so here we go, buckle up. 🫶

that was a lot. drink some water. 💀💧

heads up bestie: this page lives in ./include/net, it's dated October 2026, and it's filed under ieee80211_txq_airtime_check(9) in the Kernel API Manual. Go read the source if you need the full lore — this is just the sparknotes version. 🧚✨

later bestie, go ship some packets responsibly 💖🎀🦋
