qed_ll2_prepare_tx_packet(9)

💅 qed_ll2_prepare_tx_packet — from the Kernel API Manual, section 9 (yes, the manual manual, bestie)

okay so picture this: you're deep in the qlogic qed driver, and you need the firmware to know about a Tx packet. That's the whole vibe of this function — it's the request-for-start-Tx-BD moment where you prep a Tx packet submission to FW. Like sending a "heyyy I'm about to send something 👀" text before the actual text. Iconic.

✨ NAME ✨

qed_ll2_prepare_tx_packet — Request for start Tx BD to prepare Tx packet submission to FW.

(translation: it preps your Tx packet so it can be submitted to the firmware. the BD is the buffer descriptor, and it needs a little heads-up first. no cap.)

---

🌸 SYNOPSIS 🌸

int qed_ll2_prepare_tx_packet (void *cxt , u8 connection_handle , struct
qed_ll2_tx_pkt_info *pkt , bool notify_fw );

four arguments, one int return, zero drama (unless something fails, then it's all drama 😭).

🎀 ARGUMENTS 🎀

• cxt — Pointer to the hw-function [opaque to some]. (it's giving "don't worry about what's inside, just pass it along" energy)
• connection_handle — Connection handle. That's it. That's the whole description. It's a u8. Slay. 💅
• pkt — Info regarding the tx packet. Pointer to a struct qed_ll2_tx_pkt_info, and it's carrying all the deets about your packet.
• notify_fw — Issue doorbell to fw for this packet. It's a bool, so it's a yes/no: ring the firmware's doorbell for this packet, or keep it quiet. 🛎️

fr fr, notify_fw is the main character here — it decides whether FW gets pinged or not. Choose wisely.

---

🔥 RETURN 🔥

0 on success, failure otherwise. That's the entire rulebook. Zero means you ate and left no crumbs; anything else means something went sideways. 😭
