STRUCT BRCMF_FWS_MAC_DESCRIPTOR(9)

🦋 struct brcmf_fws_mac_descriptor(9) 🦋

okay so this is from the Kernel API Manual bestie, and it's literally the entire vibe of "firmware signalling data per node/interface" — that's the NAME, and yes we're keeping it 💅

✨ NAME ✨

struct brcmf_fws_mac_descriptor — firmware signalling data per node/interface 🫶

like... look at her. seventeen members. main character energy fr fr 👑

🎀 Members 🎀

okay bestie, member by member, no skipping, we do not do that here:

• name — name of the descriptor. it's got a whole char[16] to itself, iconic.
• occupied — slot is in use. lowkey the "seat taken" sign of the struct.
• mac_handle — handle for mac entry determined by firmware. firmware decides, not us, periodt.
• interface_id — interface index. the lil ID card 🪪
• state — current state. she contains multitudes.
• suppressed — mac entry is suppressed. shhh 🙈
• generation — generation bit. one single bit of lore.
• ac_bitmap — ac queue bitmap. bitmap queen 🌈
• requested_credit — credits requested by firmware. firmware is asking, we're just holding the clipboard.
• requested_packet — packet requested by firmware. same energy, different field.
• ea — ethernet address. the u8 ea[ETH_ALEN] classic 💖
• seq — per-node free-running sequence, sized BRCMF_FWS_FIFO_COUNT. free-running like it's never been stressed a day in its life.
• psq — power-save queue. a struct pktq, very demure, very mindful.
• transit_count — packet in transit to firmware. it's on the way!! 🚗
• suppr_transit_count — suppressed packet in transit to firmware. on the way but suppressed, so like, stealth mode 💀
• send_tim_signal — if set tim signal will be sent. that's the whole condition, no cap.
• traffic_pending_bmp — traffic pending bitmap. pending means pending bestie ⏳
• traffic_lastreported_bmp — traffic last reported bitmap. the receipts 🧾

like go read the whole friend group, they're all connected iykyk 🫶✨

ngl this page is short but she's doing the most — every field accounted for, not a single one left on read 💅

and that's the whole page bestie!! 🌟

signing off cute-style: this one's straight outta ./drivers/net/wireless/broadco... and it's dated October 2026 — and yes the footer header thing is literally struct brcm...c_descriptor(9) abbreviated because terminal columns are a scam 😭🌸

slay, go forth and signal that firmware 💖
