LIBETH_XSK_DEFINE_RUN(9)

💅 LIBETH_XSK_DEFINE_RUN 💅

okay so bestie, welcome to the LIBETH_XSK_DEFINE_RUN(9) page from the Kernel API Manual ✨ this one's a macro that literally builds a whole driver buffer process for you — the run + pass function, no cap 🫶

---

🌸 NAME 🌸

LIBETH_XSK_DEFINE_RUN — it defines a driver buffer process, aka the run + pass function 💖

---

✨ SYNOPSIS ✨

LIBETH_XSK_DEFINE_RUN (name , run , flush , populate );

like, that's the whole thing. four things go in, a function comes out 🎀

---

🦋 ARGUMENTS 🦋

• name — the name of the function you're defining. yeah. it names the thing it makes. iconic behaviour honestly 👑
• run — the name of the XDP prog run function you wanna define 🌈
• flush — the driver callback that flushes an XSk XDP_TX bulk 🔥 (yes the double backticks are in the original, we don't question the elders 💀)
• populate — the driver callback that fills an skb with HW descriptor info 🧚

ngl bestie, these are callbacks and names, so double-check you're passing what you actually mean — this macro is generating real functions for you, not just vibing 😭
