bnx2i_check_route(9)

💅 bnx2i_check_route(9) — a Kernel API Manual moment

ok so bestie, welcome to the little corner of the kernel API manual all about bnx2i_check_route, part of the bnx2i fam. it's a tiny little function but it's doing important work, and we're gonna get into it. no cap. 🦋

---

✨ NAME ✨

bnx2i_check_route — checks if the target IP route belongs to one of the NX2 devices 🎀

like, is this route ours? is it in the family? that's the whole vibe check. 🫶

---

🌸 SYNOPSIS 🌸

struct bnx2i_hba * bnx2i_check_route (struct sockaddr *dst_addr );

that's it. that's the whole call. hand it one address and it hands you back a struct bnx2i_hba *. giving very much "you give me a vibe, I give you a hardware control block." 💅

---

⭐ ARGUMENTS ⭐

• dst_addr — the target IP address, aka the thing you're asking about. drop it in and let the function decide if it belongs to a BNX2 device. 🍓

---

👑 DESCRIPTION 👑

check if the route resolves to a BNX2 device. 🔥

that's literally it, that's the whole job — it looks at the route and goes "okay, does this resolve to a BNX2 device or not?" and answers accordingly. lowkey iconic how simple it is. 💜

ngl bestie this one's short and sweet — don't overthink it, just check the route and move on. ✨

alright that's the page!! mwah 💋 this whole thing came out of ./drivers/scsi/bnx2i, October 2026 edition — go off, read the source, slay your kernel debugging era. 🎀🦋💅
