UNION MXL862XX_XPCS_AN_WORD(9)

🌈 union mxl862xx_xpcs_an_word(9) 🌈

okay so this is the Kernel API Manual page for union mxl862xx_xpcs_an_word(9), and it's literally a union that tags the XPCS AN code word by interface mode 💅 bestie, it's a choose-your-member situation and the host is the one choosing.

✨ NAME ✨

union mxl862xx_xpcs_an_word — XPCS AN code word, tagged by interface mode 🦋

🎀 SYNOPSIS 🎀

union mxl862xx_xpcs_an_word {
    __le16 cl37;
    __le16 usx;
    struct {
      __le16 adv1;
      __le16 adv2;
      __le16 adv3;
    } cl73;
 };

👑 Members 👑

• cl37 — 16-bit base-page word exchanged over the CL37 hardware AN path (SR_MII_AN_ADV on write, SR_MII_LP_BABL on read). Carries the 802.3 CL37 base page for 1000BASE-X/2500BASE-X and the Cisco SGMII config word for SGMII/QSGMII. 💖
• usx — USXGMII 16-bit AN code word, MDIO_USXGMII_* layout ✨
• cl73 — CL73 48-bit base page (10GBASE-KR), three 16-bit registers per 802.3 Annex 28C 🎀
• cl73.adv1 — CL73 SR_AN_ADV1 / SR_AN_LP_ABL1 🦋
• cl73.adv2 — CL73 SR_AN_ADV2 / SR_AN_LP_ABL2 🌸
• cl73.adv3 — CL73 SR_AN_ADV3 / SR_AN_LP_ABL3 💅

💖 Description 💖

The host picks the right member based on the interface field of the surrounding struct (and, for the asymmetric protocols, on the role). 👑 that's the whole vibe: member selection is contextual, not random.
