idpf_rx_spli...ct_csum_bits(9)

👑 idpf_rx_spli...ct_csum_bits(9)

okay so bestie, we're in the Kernel API Manual today and the page you pulled up is idpf_rx_spli...ct_csum_bits(9) — yes the title is literally truncated with dots like that, she's mysterious and she's not sorry about it 💅

✨ NAME ✨

idpf_rx_splitq_extract_csum_bits — Extract checksum bits from descriptor 🎀

🌸 SYNOPSIS 🌸

struct libeth_rx_csum idpf_rx_splitq_extract_csum_bits (const struct
       virtchnl2_rx_flex_desc_adv_nic_3 *rx_desc );

🦋 ARGUMENTS 🦋

• rx_desc — the receive descriptor 💌 that's the whole thing, she takes one descriptor and that's it, no cap

⭐ RETURN ⭐

She gives you back the parsed checksum status — that's the struct libeth_rx_csum from the synopsis, bestie. Parsed. Checksum. Status. That's the vibe check result 🙈

💜 SEE ALSO 💜

okay so this part is iconic — look at this whole friend group. The kernel file lives at ./drivers/net/ethernet/intel/idpf/idpf_txrx.c and honestly the references list goes on for a minute, so here it is in full, every single one, no edits, no cuts, we don't gatekeep here 🫶

like… that's the whole extended universe, we love a comprehensive cast 🍓

ngl bestie, if you ever need this one you're probably already deep in the idpf driver, so hydrate, take a breath, and remember: one descriptor in, parsed checksum status out 💖
