💅 update_tx_opstats(9) 💅

okay bestie, welcome to the Kernel API Manual page for update_tx_opstats — it's giving "tiny but important stats goblin" energy, and we're obsessed. 🫶

🌸 NAME 🌸

update_tx_opstats — record stats by opcode

✨ SYNOPSIS ✨

       void update_tx_opstats (struct rvt_qp *qp , struct hfi1_pkt_state *ps ,
       u32 plen );

🎀 ARGUMENTS 🎀

• qp — the qp. That's the whole description, no extra lore. 😌
• ps — transmit packet state, bestie.
• plen — the plen in dwords. Yes, dwords, not a typo. 💅

🦋 DESCRIPTION 🦋

This is a routine to record the tx opstats after a packet has been presented to the egress mechanism. That's it, that's the plot — it's literally the stats recorder showing up after the packet hits egress. ✨
