start_xmit(9)

💅 start_xmit ✨

okay so bestie, this one's from the Kernel API Manual and it's literally the whole start_xmit situation — the function that kicks an skb out the door and onto the ll2 interface. yes that's the vibe. let's get into it 🫶

---

🌸 NAME 🌸

start_xmit — she transmits an skb over the ll2 interface, that's it, that's the girlie 💅

---

✨ SYNOPSIS ✨

int start_xmit (struct qed_dev *cdev , struct sk_buff *skb , unsigned
long xmit_flags );

like, three things go in, an int comes out. iconic signature ngl 🔥

---

🎀 ARGUMENTS 🎀

• cdev — the Qed dev pointer, aka who we're doing this for 💖
• skb — the SKB. just… the SKB. that's the whole description bestie, no notes 🙈
• xmit_flags — the transmit options, and these bad boys are defined by the enum qed_ll2_xmit_flags ⭐

---

🌈 RETURN 🌈

0 on success — slay, we ate — otherwise you get an error value. so like, check it, fr fr 😭

---

🦋 SEE ALSO 🦋

• the kernel file ./include/linux/qed/qed_ll2_if.h
• start(9)
• stop(9)
• register_cb_ops(9)
• get_stats(9)

go read those too, iykyk 👑

so yeah, that's the whole page. big main character energy for a tiny transmit function honestly.

signing off from ./include/linux/qed — dated October 2026, and yes, start_xmit(9) again at the bottom because she said it twice 💜🧚‍♀️
