STRUCT MXL862XX_PCS(9)

💖 NAME 💖

okay so this is the Kernel API Manual page for struct mxl862xx_pcs(9), and bestie, it's literally the struct that links SerDes interfaces to bridge ports. no cap, that's the whole job. main character energy ✨

✨ SYNOPSIS ✨

here's the whole struct, character for character — don't touch the punctuation, she's sensitive 💅

       struct mxl862xx_pcs {
           struct phylink_pcs pcs;
           struct mxl862xx_priv *priv;
           int serdes_id;
           int slot;
           phy_interface_t interface;
        };

🦋 Members 🦋

every member, no skipping, fr fr:

• pcs — the struct phylink_pcs instance itself. that's the object, bestie 🫶
• priv — a pointer to struct mxl862xx_priv. iykyk.
• serdes_id — the SerDes instance index: 0 or 1, periodt.
• slot — the slot within the SerDes. it's 0-3 for QSGMII/QUSXGMII, and 0 otherwise. slay that distinction 🌸
• interface — the cached PHY interface, aka the last value passed to pcs_config. before the first successful pcs_config, it's PHY_INTERFACE_MODE_NA. it's used by pcs_an_restart to populate the firmware command, and by pcs_disable to skip the firmware power-down for shared (QSGMII/QUSXGMII) modes. that's important lore, don't skip it 😭
