phylink_mii...cs_get_state(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, we're diving into the Kernel API Manual today and honestly? this one's a little gem 🫶 it's the phylink_mii_c22_pcs_get_state page, and yes it does exactly what it says on the tin (read the MAC PCS state, icon behavior only 💅). let's gooo 🌈

🌸 NAME 🌸

phylink_mii_c22_pcs_get_state — read the MAC PCS state 👑

✨ SYNOPSIS ✨

void phylink_mii_c22_pcs_get_state (struct mdio_device *pcs , unsigned
int neg_mode , struct phylink_link_state *state );

🎀 ARGUMENTS 🎀

  • pcs — literally just a pointer to a struct mdio_device. that's it, that's the whole vibe 🦋
  • neg_mode — the link negotiation mode, aka the PHYLINK_PCS_NEG_xxx fam 👑
  • state — a pointer to a struct phylink_link_state, where the good stuff lands ✨

💖 DESCRIPTION 💖

so this is a helper — a lil support-system main character — for a MAC PCS that supports the 802.3 clause 22 register set, for clause 37 negotiation and/or SGMII control 🔥

what it does: reads the MAC PCS state from the MII device configured in config, then parses the Clause 37 or Cisco SGMII link partner negotiation word straight into the phylink state structure. no cap, that's the whole job 💅

and the best part? it's suitable to be directly plugged into the pcs_get_state member of the struct phylink_pcs_ops structure. plug-and-play energy fr fr 🧚✨
