STRUCT IEEE80211_MESH_FAST_TX(9)

✨ struct ieee80211_mesh_fast_tx ✨

okay bestie, welcome to the struct ieee...mesh_fast_tx(9) page from the Kernel API Manual — it's giving kernel-cache realness and I'm obsessed 💖. This one is all about the cached mesh fast tx entry, and yes, every member is here, no cap.

🌸 NAME 🌸

struct ieee80211_mesh_fast_tx — cached mesh fast tx entry.

✨ SYNOPSIS ✨

struct ieee80211_mesh_fast_tx {
    struct rhash_head rhash;
    struct ieee80211_mesh_fast_tx_key key;
    struct ieee80211_fast_tx fast_tx;
    u8 hdr[sizeof(struct ieee80211s_hdr) + sizeof(rfc1042_header)];
    u16 hdrlen;
    struct mesh_path *mpath, *mppath;
    struct hlist_node walk_list;
    unsigned long timestamp;
 };

🎀 Members 🎀

• rhash — rhashtable pointer. literally the hash-table hookup, iykyk.
• key — the lookup key for this cache entry. the way this key finds its entry… iconic.
• fast_tx — base fast_tx data. yes bestie, the base data is base-ing.
• hdr — cached mesh and rfc1042 headers. it's holding both header vibes at once.
• hdrlen — length of mesh + rfc1042. a little number for that header combo, periodt.
• mpath — mesh path corresponding to the Mesh DA. main character path energy.
• mppath — MPP entry corresponding to this DA. the MPP side of the story.
• walk_list — list containing all the fast tx entries. walk walk walk, list bestie.
• timestamp — Last used time of this entry. time-stamped and tracked, fr fr.
