bnx2x_func_state_change(9)

💅 bnx2x_func_state_change — from the Kernel API Manual ✨

okay bestie, so this one's a tiny little function page but it's literally the girl who handles Function state change transitions, and you're gonna understand her in like 30 seconds. periodt.

🌸 NAME

bnx2x_func_state_change — perform Function state change transition 🦋

---

✨ SYNOPSIS

int bnx2x_func_state_change (struct bnx2x *bp , struct
       bnx2x_func_state_params *params );

---

🎀 ARGUMENTS

• bp — the device handle 💖 like, this is the bnx2x device you're talking to, hello
• params — the parameters to perform the transaction ✨ everything you need to actually do the thing lives in here

---

🔥 DESCRIPTION

so the vibe is: you call this, and it returns 0 when the transition completed successfully — slay, we love a clean win 💅

if it fails you get a negative error code, so like, not great, but at least she's honest 😭

and here's the little plot twist 👑: you can also get a positive (EBUSY) value back, and that means there's a completion to that which is still pending. but ngl, that can only happen if RAMROD_COMP_WAIT is not set in params->ramrod_flags for asynchronous commands. iykyk — set the flag and you won't be dealing with the pending-completion jump scare 🙈

fr fr, read that again: 0 = good, negative = bad, positive (EBUSY) = still waiting on a completion, and that last one is gated on RAMROD_COMP_WAIT not being set in params->ramrod_flags for async commands. no cap.
