bnx2x_func_chk_transition(9)

💅 bnx2x_func_chk_transition — bestie edition

okay so this is a page from the Kernel API Manual (section 9, kernel devs only, iykyk ✨) and it's all about bnx2x_func_chk_transition 🦋

---

✨ NAME ✨

bnx2x_func_chk_transition — perform function state machine transition 🎀

Like, it does the vibe check on your state machine before anything moves. periodt.

---

🌸 SYNOPSIS 🌸

int bnx2x_func_chk_transition (struct bnx2x *bp , struct
bnx2x_func_sp_obj *o , struct bnx2x_func_state_params *params );

That int return? That's your answer key, bestie 💖

---

🫶 ARGUMENTS 🫶

• bp — device handle. it's the whole device, the main character, the one holding it all together 👑
• o — function info. the object we're checking out, literally 🔍
• params — state parameters. all the deets about the state stuff 🎀

---

🔥 DESCRIPTION 🔥

okay so here's the whole thing, no cap: it does two jobs and they're both iconic 💅

1. it checks if the requested command is actually legal in the current state 🙈
2. and if it is legal, it sets a next_state in the object — and that's the one that gets used later in the completion flow to set the actual state of the object ⭐

so like... it's the bouncer at the club. checks your ID (next_state), and only then do you get in (state). 🧚

the return is 0 if the requested command is a legal transition, and -EINVAL otherwise. that's the whole vibe check result, fr fr 💀

🫶 cute lil sign-off: this page came from the Kernel API Manual, source path ./drivers/net/ethernet/broadco..., dated October 2026, and yes it's filed under bnx2x_func_chk_transition(9) because that's just how we do it here 💖✨
