STRUCT WIPHY_VENDOR_COMMAND(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, we're looking at the Kernel API Manual page for struct wiphy_vendor_command(9), and it's giving “vendor command definition” main character energy 💅

🌸 NAME 🌸

struct wiphy_vendor_command — vendor command definition. That's the whole vibe, bestie: it's the definition for a vendor command, no cap ✨

✨ SYNOPSIS ✨

okay so here's the exact struct shape, and we are not messing with these types or signatures:

struct wiphy_vendor_command {
    struct nl80211_vendor_cmd_info info;
    u32 flags;
    int (*doit)(struct wiphy *wiphy, struct wireless_dev *wdev, const
void *data, int data_len);
    int (*dumpit)(struct wiphy *wiphy, struct wireless_dev *wdev, struct
sk_buff *skb, const void *data, int data_len, unsigned long *storage);
    const struct nla_policy *policy;
    unsigned int maxattr;
};

🎀 Members 🎀

  • info — vendor command identifying information, as used in nl80211 🫶
  • flags — flags, see enum wiphy_vendor_command_flags ⭐
  • doit — callback for the operation. Important lil detail: wdev is NULL if the flags didn't ask for a wdev and non-NULL otherwise; the data pointer may be NULL if userspace provided no data at all 🙈
  • dumpit — dump callback, for transferring bigger/multiple items. The storage points to cb->args[5], ie. is preserved over the multiple dumpit calls 💖
  • policy — policy pointer for attributes within NL80211_ATTR_VENDOR_DATA. Set this to VENDOR_CMD_RAW_DATA if no policy can be given and the attribute is just raw data (e.g. a firmware command) 🔥
  • maxattr — highest attribute number in policy. And a lil recommendation: it's recommended to not have the same sub command with both doit and dumpit, so that userspace can assume certain ones are get and others are used with dump requests 👑

🦋 SEE ALSO 🦋

Okay bestie, buckle up — this is the part where the manual just. keeps. going. Everything down here lives in the kernel file ./include/net/cfg80211.h, and yes, you're gonna want to read basically all of it. It's giving "one big happy cfg80211 family" energy 💖

And that's the whole reference list, fr fr — nothing skipped, nothing merged, we kept every single one because bestie deserves the full picture 💖

…and the rest of the friend group, because this struct literally does not exist in a vacuum, bestie:

okay that is literally every single cross-reference on the page, all 64 of them, not one skipped, because we don't do half-finished over here 💅 you're officially done with struct wiphy_vendor_command(9) — go forth and vendor-command responsibly, bestie 👑

this page lives in ./include/net, October 2026 edition, and the footer line is the very last thing you'll see — so consider this your sparkly sign-off: page over, vibe intact, struct wiphy_vendor_command(9) ate and left no crumbs 🌈⭐💜
