💖 ksz_port_add_dscp_prio(9) — Kernel API Manual energy 💖

Okay so bestie, this is the ksz_port_add_dscp_prio(9) page from the Kernel API Manual. It’s giving “very specific kernel API, very important little job” and honestly we’re obsessed. 🌸

🎀 NAME 🎀

ksz_port_add_dscp_prio — adds a DSCP-to-priority mapping entry for a port on a KSZ switch. That’s the whole assignment, no cap. ✨

🌈 SYNOPSIS 🌈

int ksz_port_add_dscp_prio (struct dsa_switch *ds , int port , u8 dscp ,
       u8 prio );

🦋 ARGUMENTS 🦋

• ds — pointer to the DSA switch structure (struct dsa_switch *). The main-character struct, iykyk. 💅
• port — port number for which to add the DSCP-to-priority mapping entry. Like, this is the port getting the new mapping. 🫶
• dscp — DSCP value for which to add the priority. Yes bestie, that exact DSCP value. 🌟
• prio — priority value to set. Slay. 🔥

🔥 RETURN 🔥

Returns 0 on success, or a negative error code on failure. That’s it, that’s the vibe check. 😌

bestie, remember: 0 means success, negative means failure. No extra lore, fr fr. 💀
