cfg80211_col...hange_notify(9)
💅 NAME 💅
cfg80211_color_change_notify — bestie, this is the one that tells everyone the color change is done done. Like, notify color change completion. Periodt. ✨
This is part of the Kernel API Manual, and honestly? She's a lil cutie. Let's get into it.
🦋 SYNOPSIS 🦋
int cfg80211_color_change_notify(struct net_device *dev, u8 link_id);okay so literally just two things go in, exactly like that. no cap.
🎀 ARGUMENTS 🎀
dev— the device on which the color was switched, aka the main character of this whole situation. 👑link_id— a validlink_idin case of MLO, or0for non-MLO. that's it, that's the rule, fr fr.
quick vibe check onlink_id: MLO bestie → give her a validlink_id. non-MLO bestie → just hand over a0and you're golden. 🫶
🌸 DESCRIPTION 🌸
So the whole job here is: inform the userspace that the color change has completed. That's it. She's the messenger, the group-chat announcement, the "it's giving finished" text. 💌
The way that cfg80211_color_change_notify just slides in and lets userspace know the color switch is officially wrapped up — iconic behavior, honestly. No extra drama, no lore, just the notification. ✨
⭐ RETURN ⭐
0on success — slay, we love a clean win. 💖- Non-zero on error — not the vibe, something went sideways. 😭
part 1 done, bestie — more coming, don't go anywhere 💜
🌈 SEE ALSO 🌈
okay bestie, buckle up, because this list is long — like, longer than my screen-time report long 😭 but every single one of these is fam, so we're listing them all, no skipping, no cap. All of these live in the kernel file ./include/net/cfg80211.h, k? iykyk.
