ice_write_rxq_ctx(9)

🌸 NAME 🌸

hey bestie!! welcome to ice_write_rxq_ctx(9) from the Kernel API Manual ✨ — the function that writes the Rx Queue context to hardware. no cap, this is the hardware-communication main character 🫶

---

✨ SYNOPSIS ✨

okay so the signature is giving:

int ice_write_rxq_ctx (struct ice_hw *hw , struct ice_rlan_ctx *rlan_ctx
       , u32 rxq_index );

---

🎀 ARGUMENTS 🎀

• hw — pointer to the hardware structure. literally the hardware hookup, bestie 💅
• rlan_ctx — pointer to the unpacked Rx queue context. unpacked for now — the packing is the whole point, iykyk 🦋
• rxq_index — the index of the Rx queue. which queue we're doing the thing to, fr fr 👑

---

🦋 DESCRIPTION 🦋

okay so here's the tea: this function packs the sparse Rx Queue context into the dense hardware format and writes it into the HW register space. it's lowkey giving “put the context where the hardware can see it,” and honestly? iconic 🌈

---

💅 RETURN 💅

• 0 on success 🎉
• -EINVAL if the Rx queue index is invalid 😭

so yeah, success gets you 0, and an invalid Rx queue index gets you -EINVAL. that's the whole return situation, bestie 💖
