phy_interrupt_is_valid(9)

💅 phy_interrupt_is_valid — from the Kernel API Manual bestie 🎀

okay so imagine you're deep in the kernel, poking at a PHY, and you just need to know one tiny thing: is this thing's irq actually a real irq or not. that's the whole job. that's the vibe. ✨

---

🌸 NAME 🌸

phy_interrupt_is_valid — a lil convenience function for testing a given PHY irq. yes it's literally just a check, and yes it's still important, don't @ me 🫶

---

✨ SYNOPSIS ✨

bool phy_interrupt_is_valid (struct phy_device *phydev );

it's giving "returns a bool, takes one pointer, minds its own business" 👑

---

💖 ARGUMENTS 💖

• phydev — the struct phy_device you're asking about. that's it. that's the whole argument list. one (1) boyfriend, no cap.

---

🦋 NOTE 🦋

⚠️ bestie listen to me. this function must be kept in sync with addition/removal of PHY_POLL and PHY_MAC_INTERRUPT. so if you go messing with those, you gotta come back here and update this too. no leaving it on read. fr fr 😤
