gelic_descr_prepare_rx(9)

💅 gelic_descr_prepare_rx — a Kernel API Manual moment, bestie

okay so we're in the Kernel API Manual today and the main character is gelic_descr_prepare_rx, a little function with big "give this descriptor a whole new life" energy. 🦋

---

✨ NAME ✨

gelic_descr_prepare_rx — reinitializes a rx descriptor 🌸

---

🎀 SYNOPSIS 🎀

int gelic_descr_prepare_rx (struct gelic_card *card , struct gelic_descr
*descr , bool napi_mode );

---

💖 ARGUMENTS 💖

• card — the card structure, like, the whole vibe container bestie 🫶
• descr — the descriptor we're re-initing, glow-up incoming ✨
• napi_mode — literally just answering "is it running in napi poll?" yes or no 💅

---

🌈 DESCRIPTION 🌈

returns 0 on success, <0 on failure — no cap, that's the whole mood report 😭

It allocates a brand new rx skb, iommu-maps it, and attaches it to the descriptor. Then it activates the descriptor state-wise, which is giving "main character energy, but for a buffer." 👑

Gelic RX sk_buffs must be aligned to GELIC_NET_RXBUF_ALIGN and the length must be a multiple of GELIC_NET_RXBUF_ALIGN. Not optional, not negotiable, fr fr — that's the vibe check and you will be failing it if you skip it 💀
