free_rx_ring(9)

💖 NAME — free_rx_ring(9) 💖

Okay so welcome to free_rx_ring(9), bestie. The official NAME vibe is free the RX descriptor ring. And the DESCRIPTION says it initializes the DMA RX descriptor. Yes, both of those are in the original, and I am not out here editing kernel lore. 💅

✨ SYNOPSIS ✨

void free_rx_ring (struct device *dev , struct sxgbe_rx_queue *rx_ring ,
       int rx_rsize );

🎀 ARGUMENTS 🎀

• dev — net device structure. That's the network device's whole setup energy.
• rx_ring — ring to be initialised. Yes, the argument label says initialised with an s, iconic.
• rx_rsize — ring size.

🌸 DESCRIPTION 🌸

Lowkey the entire plot: this function initializes the DMA RX descriptor. That's it, that's the description — no extra invented behavior, no "and also it does your laundry" unless the kernel file says so. Periodt. 🫶
