ixgbe_handle...ext_t_x550em(9)

💖 ixgbe_handle_lasi_ext_t_x550em 💖

okay bestie, so we're deep in the Kernel API Manual for this one — like, Kernel API Manual manual-name energy, iykyk — and the star of the show is ixgbe_handle_lasi_ext_t_x550em. she handles interrupts. she's iconic. let's get into it ✨

---

🌸 NAME 🌸

ixgbe_handle_lasi_ext_t_x550em — literally the function that handles the external Base T PHY interrupt. that's her job. that's her whole vibe. 💅

---

🦋 SYNOPSIS 🦋

int ixgbe_handle_lasi_ext_t_x550em (struct ixgbe_hw *hw , bool
*is_overtemp );

---

🎀 ARGUMENTS 🎀

• hw — pointer to hardware structure. yes queen, hand over the hardware ✨
• is_overtemp — indicates whether an overtemp event was encountered. it's telling you if things got too hot 🔥😭

---

💜 DESCRIPTION 💜

so what she does is handle the external Base T PHY interrupt — main character energy, no cap. and listen: if there's a high temperature failure alarm, she returns an error. periodt. but else, if there's a link status change, she sets up the internal/external PHY link. slay. 🫶

like, two paths, two moods:

• 🥵 high temp failure alarm → return error, we're not doing this today
• 🔗 link status change → setup internal/external PHY link, we're so back

okay that's the whole page, bestie 🌈 and for the sign-off: this little beauty comes from ./drivers/net/ethernet/intel/i... (yes the footer really does cut off like that, don't come for me 🙈) and it's dated October 2026 — future queen behavior fr fr. see you in the man pages 💅✨🎀
