STRUCT IWL_STATISTICS_HE_NTFY(9)

💅 NAME 💅

struct iwl_statistics_he_ntfy — the HE statistics struct, bestie. It's the Kernel API Manual's take on it, and yes we're getting into all of it ✨

Okay so it's a whole vibe of __le32 counters, one hdr, and a reserved at the end for luck. Let's go down the list, no skipping, fr fr 🫶

• hdr — the general statistics header received HE frames. It's giving "main character" energy, the header all the rest live under.
• rx_siga_valid_cnt — rx HE SIG-A valid.
• rx_siga_invalid_cnt — rx HE SIG-A invalid received HE frames w/ valid Sig-A.
• rx_trig_based_frame_cnt — rx HE-TB (trig-based).
• rx_su_frame_cnt — rx HE-SU.
• rx_sigb_invalid_cnt — rx (suspected) HE-MU w/ bad SIG-B.
• rx_our_bss_color_cnt — rx valid HE SIG-A w/ our BSS color.
• rx_other_bss_color_cnt — rx valid HE SIG-A w/ other BSS color.
• rx_zero_bss_color_cnt — ??? received HE-MU frames w/ good Sig-B. (Yes the ??? is literally in there 💀)
• rx_mu_for_us_cnt — match AID.
• rx_mu_not_for_us_cnt — no matched AID received HE-MU frames for us (w/ our AID).
• rx_mu_nss_ar — 0 - SISO, 1 - MIMO2.
• rx_mu_mimo_cnt — full BW RU, compressed SIG-B.
• rx_mu_ru_bw_ar — MU alloc, MHz: 0 - 2, 1 - 5, 2 - 10, 3 - 20, 4 - 40, 5 - 80, 6 - 160 received trigger frames.
• rx_trig_for_us_cnt — ???
• rx_trig_not_for_us_cnt — ??? trigger for us.
• rx_trig_with_cs_req_cnt — ???
• rx_trig_type_ar — ???
• rx_trig_in_agg_cnt — ??? basic trigger for us allocations.
• rx_basic_trig_alloc_nss_ar — ???
• rx_basic_trig_alloc_mu_mimo_cnt — ???
• rx_basic_trig_alloc_ru_bw_ar — ???
• rx_basic_trig_total_byte_cnt — ??? trig-based TX.
• tx_trig_based_cs_req_fail_cnt — ???
• tx_trig_based_sifs_ok_cnt — ???
• tx_trig_based_sifs_fail_cnt — ???
• tx_trig_based_byte_cnt — ???
• tx_trig_based_pad_byte_cnt — ???
• tx_trig_based_frame_cnt — ???
• tx_trig_based_acked_frame_cnt — ???
• tx_trig_based_ack_timeout_cnt — ??? HE-SU TX.
• tx_su_frame_cnt — ??? EDCA <--> MU-EDCA transitions.
• tx_edca_to_mu_edca_cnt — ???
• tx_mu_edca_to_edca_by_timeout_cnt — ???
• tx_mu_edca_to_edca_by_ack_fail_cnt — ???
• tx_mu_edca_to_edca_by_small_alloc_cnt — ???
• reserved — reserved. (The moment of silence at the end, we respect it 🙈)

ngl bestie, those ??? are straight from the source — the docs literally shrug at us there. Don't come for me, come for the kernel devs 💀
