💖 phy_interface_mode_is_rgmii(9) 💖

okay so this one's from the Kernel API Manual (yes, the actual kernel-api girlies) and it's honestly such a little cutie — a convenience function, no cap. 🎀

---

✨ NAME ✨

phy_interface_mode_is_rgmii — a literal convenience function for testing if a PHY interface mode is RGMII (like, all the variants, every single one, we're not picking favourites 💅)

---

🌸 SYNOPSIS 🌸

bool phy_interface_mode_is_rgmii (phy_interface_t mode );

like look at her. one arg. returns a bool. she's lowkey perfect 🫶

---

🦋 ARGUMENTS 🦋

• mode — the phy_interface_t enum 💫 that's the whole vibe, that's what you hand her, she looks at it and tells you if it's RGMII or not. icon behaviour.
