ksz_port_get_dscp_prio(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ksz_port_get_dscp_prio(9) — like, the Kernel API Manual era of my life ✨

okay so bestie, gather round, because this one is a little function from the Kernel API Manual that does exactly one thing and does it slay 💖

🌸 NAME 🌸

ksz_port_get_dscp_prio — she retrieves the priority for a DSCP value on a KSZ switch. no cap, that's the whole job 🎀

✨ SYNOPSIS ✨

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

like yes, that's the signature, copy it exactly please, we do not freestyle function signatures in this house 🙈

🦋 ARGUMENTS 🦋

  • ds — pointer to the DSA switch structure. she's the main character, everything goes through her 👑
  • port — the port number you want the priority for. which port, bestie? this port 💅
  • dscp — the DSCP value you want the priority for. a u8, so keep it cute and in range 🌈

💜 DESCRIPTION 💜

so what she actually does: this function fetches the priority value from the switch global DSCP-to-priority mapping table, for the DSCP value you specified. that's it. that's the vibe check. one lookup, one answer, iconic behaviour honestly ⭐

it's the global table, not some per-port situation — she's reading the shared one, iykyk 🔥

🫶 RETURN 🫶

  • on success: the priority value for the DSCP. slay 💖
  • on failure: a negative error code. so if you get a negative number back, that's not a priority, that's a problem, okay? check it 😭
