🧚 phylink_decode_usxgmii_word(9) 🧚

okay so bestie, welcome to the Kernel API Manual page for phylink_decode_usxgmii_word(9) — the little helper that decodes the USXGMII word from a MAC PCS. it's giving “small function, very specific job” energy and honestly? iconic. ✨

✨ NAME ✨

phylink_decode_usxgmii_word — decode the USXGMII word from a MAC PCS 💅

🌸 SYNOPSIS 🌸

void phylink_decode_usxgmii_word (struct phylink_link_state *state ,
uint16_t lpa );

🎀 ARGUMENTS 🎀

• state — a pointer to a struct phylink_link_state. yes bestie, it points at the state struct, that's the whole assignment. 🫶
• lpa — a 16 bit value which stores the USXGMII auto-negotiation word. 16 bits of auto-negotiation goodness, no cap. ✨

🦋 DESCRIPTION 🦋

so this is a helper for MAC PCS supporting the USXGMII protocol and the auto-negotiation code word. it decodes the USXGMII code word and populates the corresponding fields (speed, duplex) into the phylink_link_state structure. that's the vibe: code word goes in, speed and duplex fields get filled out. 💖
