💖 mdio45_links_ok(9) 💖

okay bestie, welcome to the Kernel API Manual ✨ — we're doing mdio45_links_ok(9) today, and it's literally the vibe check for your link status 👑

🌸 NAME 🌸

mdio45_links_ok — is link status up/OK 💅

💅 SYNOPSIS 💅

int mdio45_links_ok (const struct mdio_if_info *mdio , u32 mmd_mask );

🎀 ARGUMENTS 🎀

• mdio — the MDIO interface, aka the main character here 🫶
• mmd_mask — the mask for MMDs to check 🔍

🦋 DESCRIPTION 🦋

Returns 1 if the PHY reports link status up/OK, and 0 otherwise. No cap, that's the whole mood 💀✨

mmd_mask is normally mdio->mmds, but if loopback is enabled, the MMDs being bypassed should be excluded from the mask. Like, don't check the ones you're skipping, bestie 🙈💅
