ENUM QLINK_TLV_ID(9)

🎀 NAME

okay so this is the enum qlink_tlv_id(9) page from the Kernel API Manual, and it's literally just list of TLVs that Qlink messages can carry. that's the whole vibe. TLVs, bestie. it's giving "type-length-value catalog" and honestly? we respect it 💅

like, all 28 of them, in order, no notes 🔥

🦋 Constants

so the tea here is: most of these have no description AT ALL on this page. the source literally says -- undescribed -- and honestly, iconic mystery behavior. keeping it 100% accurate:

• QTN_TLV_ID_FRAG_THRESH — -- undescribed --, so we're left guessing 🫠
• QTN_TLV_ID_RTS_THRESH — -- undescribed --, no crumbs.
• QTN_TLV_ID_SRETRY_LIMIT — -- undescribed --, the manpage said nothing.
• QTN_TLV_ID_LRETRY_LIMIT — -- undescribed --, silent treatment fr.
• QTN_TLV_ID_REG_RULE — -- undescribed --, blank. empty. nada.
• QTN_TLV_ID_CHANNEL — -- undescribed --, mystery box behavior 💀
• QTN_TLV_ID_CHANDEF — -- undescribed --, same energy.
• QTN_TLV_ID_BITMAP — ok this one has actual lore 👑 it's a data representing a bitmap that is used together with other TLVs:
  • enum qlink_sta_info — used to indicate which statistic carried in QTN_TLV_ID_STA_STATS is valid.
  • enum qlink_hw_capab — listing wireless card capabilities.
  • enum qlink_driver_capab — listing driver/host system capabilities.
  • enum qlink_chan_stat — used to indicate which statistic carried in QTN_TLV_ID_CHANNEL_STATS is valid.
• QTN_TLV_ID_STA_STATS — per-STA statistics as defined by struct qlink_sta_stats. and bestie, only the valid values are marked as such in a bitmap carried by QTN_TLV_ID_BITMAP ✨
• QTN_TLV_ID_COVERAGE_CLASS — -- undescribed --, we know nothing 💔
• QTN_TLV_ID_IFACE_LIMIT — -- undescribed --, ghosted by the docs.
• QTN_TLV_ID_CHANNEL_STATS — -- undescribed --, no context given.
• QTN_TLV_ID_KEY — -- undescribed --, keeping secrets fr 🔐
• QTN_TLV_ID_SEQ — -- undescribed --, no comment.
• QTN_TLV_ID_IE_SET — -- undescribed --, that's it, that's the entry.
• QTN_TLV_ID_EXT_CAPABILITY_MASK — -- undescribed --, nothing to report.
• QTN_TLV_ID_ACL_DATA — -- undescribed --, head empty, no thoughts.
• QTN_TLV_ID_BUILD_NAME — -- undescribed --, unnamed (ironically).
• QTN_TLV_ID_BUILD_REV — -- undescribed --, no revision notes either.
• QTN_TLV_ID_BUILD_TYPE — -- undescribed --, type unspecified, slay.
• QTN_TLV_ID_BUILD_LABEL — -- undescribed --, label unlabeled 😭
• QTN_TLV_ID_HW_ID — -- undescribed --, no ID card shown.
• QTN_TLV_ID_CALIBRATION_VER — -- undescribed --, uncalibrated documentation.
• QTN_TLV_ID_UBOOT_VER — -- undescribed --, bootloader lore withheld.
• QTN_TLV_ID_RANDOM_MAC_ADDR — -- undescribed --, appropriately random info.
• QTN_TLV_ID_WOWLAN_CAPAB — -- undescribed --, no capabilities listed here.
• QTN_TLV_ID_WOWLAN_PATTERN — -- undescribed --, pattern not found.
• QTN_TLV_ID_IFTYPE_DATA — finally, a description! it's supported band data 📶

real talk: don't go inventing meanings for the -- undescribed -- ones, bestie. the page says what it says and nothing more 🫶

like. that's the whole extended universe 🌈
