💖 ieee802154_is_ackreq(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ this one's a tiny little function but it's a whole vibe, trust. it lives in the kernel and it's about the 802.15.4 life 🦋

---

✨ NAME ✨

ieee802154_is_ackreq — checks if the acknowledgment request bit is set 👀 literally that's her whole job and she ate

---

🌸 SYNOPSIS 🌸

bool ieee802154_is_ackreq (__le16 fc );

so she takes one thing and gives you back a bool — yes/no, slay/not slay, ack/ no ack 💅

---

🎀 ARGUMENTS 🎀

• fc — the frame control bytes, and listen, they're in little-endian byteorder bestie. little-endian. don't come at her with big-endian bytes, she will not be decoding that 🙈

---

🦋 SEE ALSO 🦋

like, go read the kernel file itself, it's giving main character energy:

• ./include/linux/ieee802154.h enum
• ieee802154_filtering_level(9)
• ieee802154_is_secen(9)
• ieee802154_is_intra_pan(9)
• ieee802154_is_valid_psdu_len(9)
• ieee802154_is_valid_extended_unicast_addr(9)
• ieee802154_is_broadcast_short_addr(9)
• ieee802154_is_unspec_short_addr(9)
• ieee802154_is_valid_src_short_addr(9)
• ieee802154_random_extended_addr(9)

ngl that's a whole friend group and they all live together in the same header 🫶 iykyk

💀 quick reminder: fc is little-endian, so if you're out here passing raw bytes with the wrong byteorder, that's on you, not on her ✨

okay that's the whole page, no cap 🧚 this cutie came from the ./include/linux source, stamped October 2026 in the Kernel API Manual — mwah, go read your frame control bytes responsibly 💜🎀
