ixgbe_setup...ane_x550em_a(9)

🦋 ixgbe_setup_fc_backplane_x550em_a(9) — the flow control glow-up

okay so this is a page from the Kernel API Manual, section 9 — yes, the header up top is truncated like ixgbe_setup...ane_x550em_a(9) because the real name is a whole mouthful and honestly the man page formatter was fighting for its life 💀 but the actual function is ixgbe_setup_fc_backplane_x550em_a, and she's the main character here.

---

✨ NAME ✨

ixgbe_setup_fc_backplane_x550em_a — sets up flow control, bestie. that's the whole vibe.

---

🎀 SYNOPSIS 🎀

int ixgbe_setup_fc_backplane_x550em_a (struct ixgbe_hw *hw );

---

🌸 ARGUMENTS 🌸

• hw — pointer to the hardware structure. yes queen, hand her the hardware and let her cook 🫶

---

💜 DESCRIPTION 💜

So basically: this one gets called at init time to set up flow control. That's it, that's the lore. It's giving "quietly essential background character who actually runs the whole friend group" energy — you don't see her doing much, but nothing works without her ✨

ngl the original page is short and she knows it, but every detail is here, no cap — nothing got left on read 💅

🔥 SEE ALSO 🔥

first up, the kernel file she lives in (iconic address, no notes):

okay that's the whole page, you ate that 💖 tiny little sign-off for the footer girlies: this came from the source path ./drivers/net/ethernet/intel/i... (truncated, we stan an ellipsis), dated October 2026, and the page answers to ixgbe_setup...ane_x550em_a(9) when it's in a rush 🎀 slay, go read the kernel source, ily, bye 🦋
