t7xx_dpmaif_tx_send_skb(9)

🎀 NAME 🎀

t7xx_dpmaif_tx_send_skb — add skb to the transmit queue. This is the Kernel API Manual entry, bestie, and yes it's giving “queue handoff realness” 💅✨

✨ SYNOPSIS ✨

int t7xx_dpmaif_tx_send_skb (struct dpmaif_ctrl *dpmaif_ctrl , unsigned
       int txq_number , struct sk_buff *skb );

🫶 ARGUMENTS 🫶

• dpmaif_ctrl — pointer to struct dpmaif_ctrl. That's the control struct, no cap 🦋
• txq_number — queue number to xmit on. Pick your queue, queen 👑
• skb — pointer to the skb to transmit. The packet bestie in question 💌

💅 DESCRIPTION 💅

Okay so it adds the skb to the queue of the skbs to be transmit 🎀 Then it wakes up the thread that push the skbs from the queue to the HW. Literally the “put it in the queue and poke the thread” moment, fr fr ✨

😭 RETURN 😭

• 0 — Success. Slay 💖
• -EBUSY — Tx budget exhausted. 😭 In normal circumstances t7xx_dpmaif_add_skb_to_ring must report the txq full state to prevent this error condition. That's the important caveat, bestie — don't skip it 🫶
