SET_IEEE80211_DEV(9)

💖 SET_IEEE80211_DEV 💖

okay bestie, gather round, because this one's from the Kernel API Manual (section 9, yes that section) and it's literally the tiniest little function with the biggest "I'm the main character" energy in the whole mac80211 extended universe. 💅

✨ NAME ✨

SET_IEEE80211_DEV — set device for 802.11 hardware 🫶

Like, that's it. That's the whole job. It sets the device for your 802.11 hardware. Iconic, minimal, no notes.

🦋 SYNOPSIS 🦋

void SET_IEEE80211_DEV (struct ieee80211_hw *hw , struct device *dev );

not a return value in sight (it's void, she gives nothing back and honestly? respect), two args, go off queen 👑

🎀 ARGUMENTS 🎀

• hw — the struct ieee80211_hw to set the device for 🌸 (this is the 802.11 hardware thingy you're attaching stuff to)
• dev — the struct device of this 802.11 device ⭐ (this is the actual device you're pointing at, iykyk)

💜 SEE ALSO 💜

right so, this is the part where I need you to sit down and hydrate first 🍓 because the see-also list is not playing around. Every single one of these is from the kernel file ./include/net/mac80211.h, and it's giving "the entire group chat got added to the same thread" energy. no cap, here we go 😭

still with me? good, because we're only like a tenth of the way through, and the way that this list just keeps going is genuinely sending me 💀
