ieee80211_s...023_mesh_hdr(9)

✨ ieee80211_strip_8023_mesh_hdr 💅

okay so bestie, real talk — you're in the Kernel API Manual right now, and this page is about one very specific little cleanup job. Let's get into it 🫶

🌸 NAME 🌸

ieee80211_strip_8023_mesh_hdr — literally strips the mesh header off frames that got converted to 802.3. that's the whole vibe. 🎀

⭐ SYNOPSIS ⭐

int ieee80211_strip_8023_mesh_hdr (struct sk_buff *skb );

🦋 ARGUMENTS 🦋

skb — the 802.3 frame that's currently carrying an embedded mesh header inside it. yes, it's in there. we're getting it out. 💅

🔥 DESCRIPTION 🔥

So here's the situation, and honestly it's giving "left my stuff at your place" energy 😭

This function strips the mesh header. And like — why is it even there? Because ieee80211_data_to_8023 left it behind, tucked in as part of the MSDU data. So we're cleaning that up now. slay. ✨

And it doesn't just delete and dip 🏃‍♀️ — it also moves any source/destination addresses from the mesh header over to the ethernet header (if present). so if there are addresses to relocate, they get relocated. iconic behavior, no cap.

ngl, that "if present" is doing a lot of work in that sentence — the ethernet header might not be there, so the address-moving only happens when it is. don't come for me, that's literally what it says 💀

💖 RETURN 💖

0 on success 🎉
Non-zero on error 😭

aaand that's the whole page for this one, bestie — the rest is still loading, so hang tight 🧚‍♀️🌸

👀 SEE ALSO 👀

okay bestie, buckle up, because this is the part of the manpage where it just... introduces you to literally everyone it knows 💅 it's giving "and these are my 400 closest friends." no cap, every single one of these is a real page in section 9 of the Kernel API Manual, so if your brain went "wait what's that" at any point in the last two parts, the answer is down here somewhere 🫶

it all starts with the kernel file ./include/net/cfg80211.h (that's the origin story, the main character's birthplace ✨), and then immediately: Introduction(9), Device registration(9), enum ieee80211_channel_flags(9), struct ieee80211_channel(9), enum ieee80211_rate_flags(9), enum ieee80211_bss_type(9), enum ieee80211_privacy(9), struct ieee80211_rate(9), struct ieee80211_he_obss_pd(9), struct cfg80211_he_bss_color(9), struct ieee80211_sta_ht_cap(9), struct ieee80211_sta_vht_cap(9), struct ieee80211_sta_he_cap(9), struct ieee80211_eht_mcs_nss_supp(9), struct ieee80211_sta_eht_cap(9), struct ieee80211_sta_uhr_cap(9), struct ieee80211_sband_iftype_data(9), enum ieee80211_edmg_bw_config(9), struct ieee80211_edmg(9), struct ieee80211_sta_s1g_cap(9), struct ieee80211_supported_band(9), _ieee80211_set_sband_iftype_data(9), ieee80211_set_sband_iftype_data(9), for_each_sband_iftype_data(9), ieee80211_get_sband_iftype_data(9), ieee80211_get_he_iftype_cap(9), ieee80211_get_he_6ghz_capa(9), ieee80211_get_eht_iftype_cap(9), ieee80211_get_uhr_iftype_cap(9), wiphy_read_of_freq_limits(9) — that's the band-and-capabilities friend group, the ones who know what your radio can actually do 🦋
