bdx_rx_receive(9)

okay so bestie, welcome to bdx_rx_receive(9) from the Kernel API Manual 🫶 this is the page where full packets get pulled from the fifo and handed off, and we are keeping every single detail cute and intact ✨

🌸 NAME 🌸

bdx_rx_receive — receives full packets from the RXD fifo and passes them to the OS. like, the whole point is grabbing complete packets and handing them off 💌

✨ SYNOPSIS ✨

int bdx_rx_receive (struct bdx_priv *priv , struct rxd_fifo *f , int
       budget );

🎀 ARGUMENTS 🎀

• priv — nic's private structure. it's the NIC's own lil private struct, okay? 💖
• f — the RXF fifo that needs skbs. yes, this fifo is asking for skbs, feed it 🍓
• budget — maximum number of packets to receive. that's the cap on how many packets we're receiving, periodt 💅

💅 NOTE 💅

okay, important vibe check 🚨 a special treatment is given to non-continuous descriptors that start near the end, wrap around, and continue at the beginning. a second part is copied right after the first, and then the descriptor is interpreted as normal. the fifo has an extra space to allow such operations — that's the whole trick, no cap 🧚✨
