bnx2x_set_pbd_csum_enc(9)

💅 bnx2x_set_pbd_csum_enc(9) — like, the kernel API manual bestie 🎀

okay so welcome to the bnx2x_set_pbd_csum_enc page from the Kernel API Manual, bestie — buckle up, this one's short but it's giving ✨niche driver magic✨

---

✨ NAME ✨

bnx2x_set_pbd_csum_enc — update PBD with checksum and return header length 🧚

like, that's literally the whole job. PBD gets its checksum glow-up, and the function hands you back the header length. slay 💅

---

🌸 SYNOPSIS 🌸

u8 bnx2x_set_pbd_csum_enc (struct bnx2x *bp , struct sk_buff *skb , u32
*parsing_data , u32 xmit_type );

notice the return type is u8, okay? it's not out here returning some giant struct, it's a lil byte. iconic behavior honestly 🫶

🦋 ARGUMENTS 🦋

• bp — the driver handle 💖 your main character pointer, fr fr
• skb — the packet skb 🎀 the actual packet we're out here fussing over
• parsing_data — data to be updated ✨ like, this is the thing getting rewritten, no cap
• xmit_type — xmit flags 🌈 the flags that tell you what kind of transmit situation we're in

🔥 DESCRIPTION 🔥

57712/578xx related, when skb has encapsulation 👑

that's it. that's the whole description. it's giving minimalist. it's giving "iykyk". if you're on 57712/578xx silicon and your skb is carrying encapsulation, this is your function, periodt 💀

quick vibe check: the manpage really is this brief — no extra lore, no secret options, nothing hidden in the back. just those two facts and a whole lot of aura 🧚
