💖 NAME 💖

Okay bestie, welcome to the t4_ethrx_handler(9) page from the Kernel API Manual ✨ This function is t4_ethrx_handler — and its whole iconic job is to process an ingress ethernet packet. Periodt. 🦋

✨ SYNOPSIS ✨

int t4_ethrx_handler (struct sge_rspq *q , const __be64 *rsp , const
       struct pkt_gl *si );

🎀 ARGUMENTS 🎀

• q — the response queue that received the packet 💌
• rsp — the response queue descriptor holding the RX_PKT message 🔥
• si — the gather list of packet fragments 🧚

💅 DESCRIPTION 💅

Process an ingress ethernet packet and deliver it to the stack. That's the whole plot, bestie — it processes an ingress ethernet packet and delivers it to the stack. No cap. 💜
