STRUCT IEEE80211_ENH_CRIT_UPD(9)

💖 NAME

okay bestie, welcome to the struct ieee80211_enh_crit_upd(9) page in the Kernel API Manual — yes, we're doing kernel structs today and it's lowkey iconic. This one is struct ieee80211_enh_crit_upd — the enhanced critical update (UHR) struct. No cap, it's tiny, but it still ate.

✨ SYNOPSIS

Here's the whole struct, exactly as it shows up:

struct ieee80211_enh_crit_upd {
    u8 v;
};

🎀 Members

• v — value of the enhanced critical update data. To parse the bits, see IEEE80211_ENH_CRIT_UPD_*, iykyk.
