*netdev );

✨ ARGUMENTS ✨

  • skb — a packet skbuff pointer. the little data baby you're handing over 💌
  • netdev — the kernel network device. the context, the setting, the whole scene it happens in 🌈

🔥 RETURN 🔥

  • NETDEV_TX_BUSY — returned if the Tx Queue is full. like, no room, try again later, the queue said "I'm booked" 💀
  • NETDEV_TX_OK — returned if it was successfully enqueued to the hardware Tx Queue. slay, it ate, it's in 👑
