ef4_init_rx_buffers(9)

🌸 NAME 🌸

Okay bestie, welcome to the ef4_init_rx_buffers(9) page from the Kernel API Manual 💅 — this one is all about how to create EF4_RX_BATCH page-based RX buffers.

✨ SYNOPSIS ✨

int ef4_init_rx_buffers (struct ef4_rx_queue *rx_queue , bool atomic );

🎀 ARGUMENTS 🎀

• rx_queue — Efx RX queue. That's the queue we're setting up, no cap.
• atomic — control memory allocation flags. It's the vibe check for how memory gets allocated.

🦋 DESCRIPTION 🦋

So here's the tea: this allocates a batch of pages, maps them for DMA, and populates struct ef4_rx_buffers for each one. Return a negative error code or 0 on success. 🫶

And important detail, bestie: if a single page can be used for multiple buffers, then the page will either be inserted fully, or not at all. It's giving all-or-nothing energy — no half-in, half-out situations. ✨
