mii_check_link(9)

💖 NAME 💖

mii_check_link — check MII link status. This page is from the Kernel API Manual, and it’s giving tiny-but-iconic helper energy, fr fr.

✨ SYNOPSIS ✨

void mii_check_link (struct mii_if_info *mii );

🎀 ARGUMENTS 🎀

• mii — MII interface. That’s the one and only arg, bestie.

🦋 DESCRIPTION 🦋

Okay so here’s the tea: if the link status changed — literally previous != current — then it calls netif_carrier_on if the current link status is Up, or it calls netif_carrier_off if the current link status is Down. No cap, that’s the whole move. 💅
