STRUCT IPOIB_TXREQ(9)

🦋 NAME

Okay so bestie, this is struct ipoib_txreq(9) — the IPOIB transmit descriptor. It’s giving kernel-struct realness, and we are gonna walk through every field together because nothing here is getting left on read. Periodt. 💅

✨ SYNOPSIS

Here’s the exact struct shape, untouched and iconic:

       struct ipoib_txreq {
           struct sdma_txreq           txreq;
           struct hfi1_sdma_header     *sdma_hdr;
           int sdma_status;
           int complete;
           struct hfi1_ipoib_dev_priv *priv;
           struct hfi1_ipoib_txq      *txq;
           struct sk_buff             *skb;
        };

👑 Members

Every member, and what it’s serving:

• txreq — the sdma transmit request. Main character energy, fr fr.
• sdma_hdr — the 9b ib headers. Yes, exactly that. No notes.
• sdma_status — the status returned by sdma engine. It’s giving receipts.
• complete — non-zero implies complete. That’s the whole vibe check.
• priv — the ipoib netdev private data. Lowkey essential.
• txq — the txq on which skb was output. Slay.
• skb — the skb to send. Obviously.
