👑 DESCRIPTION 👑

so here's the tea ☕ — this function configures the MDIX mode of the LAN937x TX PHY, and it decides everything based on the mdix_ctrl field of the phy_device structure 💫

the MDIX mode can be set to one of these three:

• MDI — straight-through, no crossover energy 🌈
• MDIX — crossover, we're crossing those wires bestie 🔀
• AUTO — auto-MDIX, it figures it out itself, main character behaviour 👑

and then — important — if the mode is not recognized, it just returns 0 without making any changes 🙈 no drama, no edits, just vibes and a zero 😭

⭐ RETURN ⭐

• 0 on success 🎉
• a negative error code on failure 💀
