🌸 igb_reset_mdicnfg_82580 — NAME ✨

okay so bestie, this is igb_reset_mdicnfg_82580 from the Kernel API Manual — and it's literally the function that resets the MDICNFG destination and com_mdio bits. that's the whole vibe. 💅

🦋 SYNOPSIS

s32 igb_reset_mdicnfg_82580 (struct e1000_hw *hw );

like, it takes one thing and gives you back an s32. no cap. ✨

🎀 ARGUMENTS

  • hw — pointer to the HW structure 🫶 that's it, that's the whole argument list, she's lowkey low-maintenance.

💖 DESCRIPTION

so here's the tea: this function resets the MDICNFG.Destination and MDICNFG.Com_MDIO bits, and it decides what to set them to based on the values it finds in the EEPROM. 👑

why does that matter? because there's this whole issue where those bits don't get restored from EEPROM after a reset — which is giving broken, honestly — and this function is the fix. it goes and re-applies them so everything's slaying the way it should. 💀✨
