ENUM NL80211_BAND_ATTR(9)

💖 enum nl80211_band_attr(9) — band attributes 💖

okay so bestie, gather round, because this is the manual page for enum nl80211_band_attr(9) and it's literally the enum that says "here's what a band looks like" — band attributes, periodt. if you're poking at nl80211 and need to describe a frequency band to the kernel, this is the vibe check you're passing. no cap. 🦋

};

like, that's the whole lineup, and every single one of them is iconic in its own way. let's go through them one by one, no skipping 💅

🎀 Constants 🎀

• __NL80211_BAND_ATTR_INVALID — attribute number 0 is reserved. it's the "don't touch, this seat's taken" of the enum 🪑
• NL80211_BAND_ATTR_FREQS — the supported frequencies in this band, and it's an array of nested frequency attributes. nested. like a little frequency family tree 🌈
• NL80211_BAND_ATTR_RATES — the supported bitrates in this band, an array of nested bitrate attributes. same energy, but for rates 🏃‍♀️
• NL80211_BAND_ATTR_HT_MCS_SET — a 16-byte attribute containing the MCS set as defined in 802.11n. sixteen. bytes. count them 🍓
• NL80211_BAND_ATTR_HT_CAPA — HT capabilities, as in the HT information IE ✨
• NL80211_BAND_ATTR_HT_AMPDU_FACTOR — A-MPDU factor, as in 11n 🌸
• NL80211_BAND_ATTR_HT_AMPDU_DENSITY — A-MPDU density, as in 11n. yes it's a different attribute from the factor, don't mix them up bestie 😭
• NL80211_BAND_ATTR_VHT_MCS_SET — a 32-byte attribute containing the MCS set as defined in 802.11ac. double the bytes, double the slay 💅
• NL80211_BAND_ATTR_VHT_CAPA — VHT capabilities, as in the HT information IE 👑
• NL80211_BAND_ATTR_IFTYPE_DATA — a nested array attribute, with each entry using attributes from enum nl80211_band_iftype_attr. so it's nested arrays of other enums' attributes. we love a delegation moment 🫶
• NL80211_BAND_ATTR_EDMG_CHANNELS — a bitmap that indicates the 2.16 GHz channel(s) that are allowed to be used for EDMG transmissions. Defined by IEEE P802.11ay/D4.0 section 9.4.2.251. write that section number down, it's giving citation realness 🔥
• NL80211_BAND_ATTR_EDMG_BW_CONFIG — the Channel BW Configuration subfield encodes the allowed channel bandwidth configurations. Defined by IEEE P802.11ay/D4.0 section 9.4.2.251, Table 13. note: Table 13 this time, not just the section. details matter 🌟
• NL80211_BAND_ATTR_S1G_MCS_NSS_SET — S1G capabilities, supported S1G-MCS and NSS set subfield, as in the S1G information IE, 5 bytes. five. bytes. 🎀
• NL80211_BAND_ATTR_S1G_CAPA — S1G capabilities information subfield as in the S1G information IE, 10 bytes. yeah it's a different one than the line above, and it's 10 bytes, and yes I'm obsessed with the byte counts ⭐
• __NL80211_BAND_ATTR_AFTER_LAST — internal use. that's it. that's the description. don't @ her, she's busy 🙈
• NL80211_BAND_ATTR_MAX — highest band attribute currently defined. the ceiling. the final boss. the main character of the upper bound 💀

like I said. long long. but you read all of it and I'm proud of you 🫶✨

and that's the whole page bestie, you ate that 💅🌸 this cutie came out of ./include/uapi/linux and it's dated October 2026, so jot that down and go be iconic with your band attributes. mwah 🎀💖
