💅 struct hfi1_ipoib_txq(9) 💅

okay bestie, you're in the Kernel API Manual (yes, that's the manual name, we're fancy here ✨) and today's main character is struct hfi1_ipoib_txq — literally IPOIB per Tx queue information, no cap. 🎀

✨ NAME ✨

struct hfi1_ipoib_txq — IPOIB per Tx queue information 🦋

🌸 SYNOPSIS 🌸

struct hfi1_ipoib_txq {
    struct napi_struct napi;
    struct hfi1_ipoib_dev_priv *priv;
    struct sdma_engine *sde;
    struct list_head tx_list;
    union hfi1_ipoib_flow flow;
    u8 q_idx;
    bool pkts_sent;
    struct iowait wait;
    struct hfi1_ipoib_circ_buf tx_ring;
 };

like, that's the whole struct, laid out immaculate 💅

okay so vibe check on every single field, one by one, we are NOT skipping any:

• napi — pointer to tx napi interface 🔥

literally every single one, we ate and left no crumbs 😭
