dpni_set_offload(9)

💅 dpni_set_offload(9) — like, the DPNI offload config setter, bestie

okay so this is a page from the Kernel API Manual (that's the manual name, iykyk) and it's all about dpni_set_offload — the little function that sets your DPNI offload configuration. genuinely iconic of it. 🎀

---

✨ SYNOPSIS ✨

int dpni_set_offload (struct fsl_mc_io *mc_io , u32 cmd_flags , u16
token , enum dpni_offload type , u32 config );

like yes, that's the whole signature, no cap. five args, one int back. 💖

🌸 ARGUMENTS 🌸

• mc_io — pointer to the MC portal's I/O object. it's giving "your ticket to the portal", fr fr.
• cmd_flags — command flags; one or more of 'MC_CMD_FLAG_'. pick your flags, queen. 🦋
• token — token of the DPNI object. it's literally the DPNI's little name tag.
• type — type of DPNI offload. which flavor of offload are we doing today 💅
• config — offload configuration. for checksum offloads, a non-zero value enables the offload. so like, 0 = off, not-0 = on, periodt.

⭐ RETURN ⭐

soooo the RETURN section is, um, empty in the original — crickets 🦗 — nothing listed here, so there's nothing for me to invent. moving on bestie, don't @ me.

🫶 DESCRIPTION 🫶

⚠️ warning: allowed only when DPNI is disabled

like, that's the whole description and it's also the whole warning. the DPNI has to be disabled first or this is a no-go. respect the vibe check. 😭
