💖 lpfc_build_hbq_profile5(9) 💖

okay bestie, welcome to the Kernel API Manual ✨ this one's a little kernel-side cutie and honestly she's giving "quiet but powerful" energy. no cap.

---

✨ NAME ✨

lpfc_build_hbq_profile5 — Set up the HBQ Selection Profile 5 🎀

---

🦋 SYNOPSIS 🦋

void lpfc_build_hbq_profile5 (struct config_hbq_var *hbqmb , struct
lpfc_hbq_init *hbq_desc );

literally that's the whole signature, periodt 💅

---

🌸 ARGUMENTS 🌸

• hbqmb — pointer to the HBQ configuration data structure in mailbox command. yes girl it's the config data, sitting pretty in the mailbox command 🫶
• hbq_desc — pointer to the HBQ selection profile descriptor. that's the descriptor bestie, the profile's little ID card 💳

---

💜 DESCRIPTION 💜

so the Host Buffer Queue (HBQ) Selection Profile 5 specifies a header HBQ. iconic. 💫

the HBA tests the initial frame of an incoming sequence using the frame's R_CTL/TYPE fields — with words 10:15 — and then it performs the Sequence Length Test and the Byte Field Test using the fields in the Selection Profile 5 extension, a.k.a. words 20:31. that's the whole vibe check: words 10:15 for the test, words 20:31 for the extension fields. iykyk 🌈
