STRUCT GFAR_PRIV_TX_Q(9)

💖 NAME 💖

okay so bestie, welcome to the Kernel API Manual page for struct gfar_priv_tx_q(9) — it's literally the per tx queue structure, no cap 🎀✨

🦋 SYNOPSIS 🦋

this is the whole struct, copied exactly because we do not mess with code vibes 💅

       struct gfar_priv_tx_q {
           spinlock_t txlock;
           struct txbd8 *tx_bd_base;
           struct txbd8 *cur_tx;
           unsigned int num_txbdfree;
           unsigned short skb_curtx;
           unsigned short tx_ring_size;
           struct tx_q_stats stats;
           struct gfar_priv_grp *grp;
           struct net_device *dev;
           struct sk_buff **tx_skbuff;
           struct txbd8 *dirty_tx;
           unsigned short skb_dirtytx;
           unsigned short qindex;
           unsigned int txcoalescing;
           unsigned long txic;
           dma_addr_t tx_bd_dma_base;
        };

🌸 Members 🌸

okay these members? iconic. every single one, in order, and yes we're keeping all the details 🫶

• txlock — per queue tx spin lock, literally the lock for this queue's tx situation 🔒
• tx_bd_base — First tx buffer descriptor, the starting point bestie 💫
• cur_tx — Next free ring entry, lowkey the next spot in the ring 👑
• num_txbdfree — number of free TxBds, a whole count of free TxBds 🧮
• skb_curtx — to be used skb pointer, the skb pointer that's gonna be used 👀
• tx_ring_size — Tx ring size, periodt 💅
• stats — bytes/packets stats, all the bytes and packets tea 🍓
• grp — back pointer to the group to which this queue belongs, fr fr 🫶
• dev — back pointer to the dev structure, yup it points back to dev 🦋
• tx_skbuff — skb pointers, plural skb pointers 🌈
• dirty_tx — First buffer in line to be transmitted, first in line, main character energy 🚀
• skb_dirtytx — the last used skb pointer, the last used one, not me forgetting it 😭
• qindex — index of this queue, its little queue index number 🔥
• txcoalescing — enable/disable tx coalescing, the on/off switch vibe for tx coalescing ⭐
• txic — transmit interrupt coalescing value, the value for transmit interrupt coalescing 💜
