bnx2x_queue_chk_transition(9)

💖 bnx2x_queue_chk_transition(9) 💖

okay so bestie, welcome to the bnx2x_queue_chk_transition page from the Kernel API Manual ✨ this one is literally the vibe-check bouncer for a regular Queue's state machine, and yes it's as iconic as it sounds 🎀

---

🌸 NAME 🌸

bnx2x_queue_chk_transition — check state machine of a regular Queue 👑

---

✨ SYNOPSIS ✨

int bnx2x_queue_chk_transition (struct bnx2x *bp , struct
       bnx2x_queue_sp_obj *o , struct bnx2x_queue_state_params *params );

---

🦋 ARGUMENTS 🦋

• bp — device handle, the whole device's main character pass 🫶
• o — queue info, like all the tea about this specific queue 💅
• params — queue state, the state we're trying to slide into 🌈

---

💜 DESCRIPTION 💜

okay so first thing, the heading says (not Forwarding) — meaning this is not for Forwarding, got it? write that down 📝

What it does: it does both things, bestie. It checks whether the requested command is legal in the current state, and if it is legal, it sets a next_state in the object — and that next_state is what the completion flow will use later to set the state of the object. two-step reveal, very iconic 🔥

It returns 0 if the requested command is a legal transition, and -EINVAL otherwise. no cap, that's the whole return situation 💀
