igc_configure_rx_ring(9)

✨ NAME ✨

igc_configure_rx_ring — bestie, this is the one that configures a receive ring after Reset 💅

So real quick, this is a page from the Kernel API Manual, section 9. Yeah. We're in kernel-land now. 🧚

---

🌸 SYNOPSIS 🌸

void igc_configure_rx_ring (struct igc_adapter *adapter , struct
       igc_ring *ring );

Like, that's the whole thing. Returns nothing (void), takes two pointers, does the vibe check on your Rx ring. Slay. 👑

🎀 ARGUMENTS 🎀

• adapter — the board private structure 🫶 iykyk, it's the big per-board struct that holds all the gossip.
• ring — the receive ring that's about to get configured ✨ this is the actual one getting the glow-up.

💖 DESCRIPTION 💖

Okay so picture this: the MAC just went through a Reset 😭 and now the Rx unit is sitting there like "what do I even do now." This function is the one that pulls up, configures the Rx unit of the MAC after a reset, and gets it back on its feet. Periodt. 💅

Not me overselling it — that's literally the whole job: configure the Rx unit of the MAC after a reset. Iconic, lowkey. 🔥

Okay that's the page!! 💜 This lil masterpiece lives in ./drivers/net/ethernet/intel/igc, dated October 2026, and it's igc_configure_rx_ring(9) all day every day. Go configure some rings, main character. 🦋✨
