💖 idpf_rx_desc_rel(9) 💖

okay bestie, welcome to the Kernel API Manual — this page is literally about idpf_rx_desc_rel(9), and we're gonna get you fluent in it, no cap. ✨

🌸 NAME 🌸

idpf_rx_desc_rel — free a specific Rx q's resources. 💅

✨ SYNOPSIS ✨

Here's the exact signature, character for character, bestie — don't let the spacing jump you:

void idpf_rx_desc_rel (struct idpf_rx_queue *rxq , struct device *dev ,
u32 model );

🎀 ARGUMENTS 🎀

• rxq — the queue we're cleaning the resources from. 🧹
• dev — the device we use to free DMA memory. 🫶
• model — the queue model: single or split. 💫

💅 DESCRIPTION 💅

okay so this function frees the resources for a specific Rx queue. That's the whole vibe: one specific Rx queue, resources freed, done. 🦋

🦋 SEE ALSO 🦋

The Kernel file this lives in is ./drivers/net/ethernet/intel/idpf/idpf_txrx.c — bookmark it, bestie. 📌
