STRUCT IWL_TLC_CONFIG_CMD(9)

🦋 struct iwl_tlc_config_cmd — TLC configuration 🦋

Okay bestie, so this one is a Kernel API Manual page, and it's literally the whole deal on struct iwl_tlc_config_cmd — the TLC config struct. No cap, it's just a struct + a member-by-member glow-up tour. Let's get into it 💅

✨ SYNOPSIS ✨

Here's the whole vibe, verbatim, don't @ me:

struct iwl_tlc_config_cmd {
    __le32 sta_mask;
    __le32 phy_id;
    u8 max_ch_width;
    u8 mode;
    u8 chains;
    u8 sgi_ch_width_supp;
    __le16 flags;
    __le16 non_ht_rates;
    __le32 ht_rates[IWL_TLC_NSS_MAX][IWL_TLC_MCS_PER_BW_NUM_V4];
    __le16 max_mpdu_len;
    __le16 max_tx_op;
 };

🎀 Members 🎀

Girl. The members. Every single one, here we go:

• sta_mask — the station mask. And the tea here 🍵: in NAN we can have multiple logical stations of the same peer (like, ones that share the same TLC configuration). Multiple. Logical. Stations. Iconic behavior honestly.
• phy_id — the phy id that gets used for this TLC configuration.
• max_ch_width — the max supported channel width, straight from enum iwl_tlc_mng_cfg_cw.
• mode — it's enum iwl_tlc_mng_cfg_mode. That's it, that's the field.
• chains — a bitmask of enum iwl_tlc_mng_cfg_chains.
• sgi_ch_width_supp — a bitmap of SGI support per channel width, and you build it with BIT(enum iwl_tlc_mng_cfg_cw). Cute little bitwise moment.
• flags — a bitmask of enum iwl_tlc_mng_cfg_flags.
• non_ht_rates — a bitmap of supported legacy rates. The old-school ones, respectfully.
• ht_rates — a bitmap of enum iwl_tlc_mng_ht_rates, per <nss, channel-width> pair. And the pair indexing, iykyk:
  • 0 — 80mhz width and below
  • 1 — 160mhz
  • 2 — 320mhz
• max_mpdu_len — max MPDU length, in bytes. Bytes!! Not vibes.
• max_tx_op — max TXOP in uSecs for all AC (BK, BE, VO, VI). Set it to zero for no limit 🫶
