STRUCT MESH_SETUP(9)

📦 version 7.3.1, in nixpkgs unstable

✨ NAME ✨

struct mesh_setup — 802.11s mesh setup configuration, straight from the struct mesh_setup(9) manual page. Bestie, this is the struct that holds the setup details for an 802.11s mesh. 🫶

🌸 SYNOPSIS 🌸

struct mesh_setup {
    struct cfg80211_chan_def chandef;
    const u8 *mesh_id;
    u8 mesh_id_len;
    u8 sync_method;
    u8 path_sel_proto;
    u8 path_metric;
    u8 auth_id;
    const u8 *ie;
    size_t ie_len;
    bool is_authenticated;
    bool is_secure;
    bool user_mpm;
    u8 dtim_period;
    u16 beacon_interval;
    int mcast_rate[NUM_NL80211_BANDS];
    u32 basic_rates;
    struct cfg80211_bitrate_mask beacon_rate;
    bool userspace_handles_dfs;
    bool control_port_over_nl80211;
};

👯 Members 👯

  • chandef — defines the channel to use. 📡
  • mesh_id — the mesh ID. 🆔
  • mesh_id_len — length of the mesh ID, at least 1 and at most 32 bytes. 🔢
  • sync_method — which synchronization method to use. 🌀
  • path_sel_proto — which path selection protocol to use. 🛣️
  • path_metric — which metric to use. 📏
  • auth_id — which authentication method this mesh is using. 🔐
  • ie — vendor information elements (optional). 🎁
  • ie_len — length of vendor information elements. 📦
  • is_authenticated — this mesh requires authentication. ✅
  • is_secure — this mesh uses security. 🛡️
  • user_mpm — userspace handles all MPM functions. 🧑‍💻
  • dtim_period — DTIM period to use. ⏱️
  • beacon_interval — beacon interval to use. 📶
  • mcast_rate — multicast rate for Mesh Node [6Mbps is the default for 802.11a]. 🔥
  • basic_rates — basic rates to use when creating the mesh. 🧱
  • beacon_rate — bitrate to be used for beacons. 📣
  • userspace_handles_dfs — whether user space controls DFS operation, i.e. changes the channel when a radar is detected. This is required to operate on DFS channels. 🚨
  • control_port_over_nl80211 — TRUE if userspace expects to exchange control port frames over NL80211 instead of the network interface. 📨

💖 Description 💖

These parameters are fixed when the mesh is created. Periodt. 🎀

✨ SEE ALSO ✨

okay so this section is genuinely a journey 💀 — STRUCT MESH_SETUP(9) sits right in the middle of the cfg80211 cinematic universe, so the cross-reference list is basically the whole friend group. Grab a snack 🍓, we're going through every single one, no skips, no cap.

that's the band/capability cluster btw, it's giving "prerequisites" ✨

struct mesh_config(9) is literally right there next to us btw — that's our sibling page, hi bestie 🫶

the NAN block is so random and I'm obsessed 🌸

the wiphy_* work/lock block, we love a well-organised queue icon 🎀

ieee80211_get_mesh_hdrlen(9) and ieee80211_strip_8023_mesh_hdr(9) are our mesh besties in this list 🧚

and that's the whole list 💅 — yes it's long, yes it's giving "who invited all these", but every single one of these is a real page you can go read. the mesh stuff lives in here too, iykyk 🦋

okay so the SEE ALSO list just KEEPS GOING and honestly? it's giving group chat with 64 members and everyone's typing 💀 here's the rest of the squad, in the exact order the page serves them to you — no skipping, no cutting, we respect all of them equally 🫶

fr fr that's the whole page bestie, you ate that 💅 but before you close the tab, the little footer at the bottom is not a vibe, it's bookkeeping: this page lives in ./include/net, it's the struct mesh_setup(9) manual, and it's dated October 2026 — yes, the future, don't ask 🌈⭐ keep that in mind if you're citing her 🫶💖
