✨ __libeth_xsk_run_prog_slow ✨

okay so we're in the Kernel API Manual today bestie, and this page is literally all about __libeth_xsk_run_prog_slow — the slow-path cleanup queen 👑 of the libeth XSk world. she handles all the verdicts that aren't XDP_REDIRECT, because redirect is too busy being the main character. 💅

---

🌸 NAME 🌸

__libeth_xsk_run_prog_slow — process the non-XDP_REDIRECT verdicts 🎀

---

🦋 SYNOPSIS 🦋

u32 __libeth_xsk_run_prog_slow (struct libeth_xdp_buff *xdp , const
struct libeth_xdp_tx_bulk *bq , enum xdp_action act , int ret );

---

💖 ARGUMENTS 💖

• xdp — the buffer you're processing, bestie 🫶 that's the whole vibe
• bq — the Tx bulk used for queueing when you hit XDP_TX
• act — the verdict that needs processing, iykyk
• ret — the error code you get if XDP_REDIRECT failed 😭

---

🧚 DESCRIPTION 🧚

so this is an external helper used by __libeth_xsk_run_prog — which means no cap, do not call it directly, please and thank you 🙈

here's the tea: XDP_REDIRECT is the most common and the hottest verdict on XSk, so it gets processed inline (she's built different ⚡). everything else goes here for out-of-line processing, and redirect errors get to hang out here too. it's giving "backstage crew keeping the show running" energy fr fr 💜

---

⭐ RETURN ⭐

the libeth_xdp XDP prog verdict. that's it, that's the return ✨
