STRUCT OCB_SETUP(9)
π¦ struct ocb_setup(9) β the 802.11p OCB mode setup config, bestie π
okay so picture this: you're in the Kernel API Manual, section 9, and you've stumbled into struct ocb_setup β literally the little bundle of settings that describes how to set up 802.11p OCB mode. it's small, it's iconic, it's giving "one job and I do it well." π
β¨ NAME β¨
struct ocb_setup β the 802.11p OCB mode setup configuration. that's it. that's the whole vibe. no cap.
β¨ SYNOPSIS β¨
struct ocb_setup {
struct cfg80211_chan_def chandef;
};
look at her. one member. absolutely unbothered. π«Ά
β¨ Members β¨
chandefβ this is the one that actually matters, ngl: it defines the channel to use. that's the whole assignment. the channel. the β¨channelβ¨. π
β¨ Description β¨
so here's the tea β β these parameters are fixed when connecting to the network. like, you set them going in, and they stay put. no take-backs, no mid-connection glow-ups. periodt. π
okay so that's the struct itself, and honestly she ate β minimal, readable, main character energy with zero filler. but we are so not done here, because there's more coming π
π SEE ALSO π
okay bestie, this is the part where the manpage just tags everyone in the group chat π«Ά. every single one of these is a (9) page, cross-linked, so there's like a whole ecosystem going on here. no cap, this is a long one. let's go π
