ixgbe_identify_phy_fw(9)

🦋 ixgbe_identify_phy_fw(9) — the Kernel API Manual one, bestie 🦋

okay so picture this: you're deep in the ixgbe driver, it's giving Intel ethernet energy, and you need to know what PHY you're dealing with. That's this function. Welcome to the group chat 💅

---

✨ NAME ✨

ixgbe_identify_phy_fw — Get PHY type based on firmware command 🫶

---

🌸 SYNOPSIS 🌸

int ixgbe_identify_phy_fw (struct ixgbe_hw *hw );

---

🎀 ARGUMENTS 🎀

• hw — pointer to hardware structure. that's it. that's the whole argument. she's lowkey simple like that 💖

---

💜 DESCRIPTION 💜

Returns error code. yes literally that's the whole description, no cap, the docs said what they said 😭

ngl bestie, this is one of those one-liner descriptions, so don't come for me — I'm just the messenger 🧚
