bdx_tx_transmit(9)

💖 NAME 💖

okay so bestie, this is bdx_tx_transmit(9) from the Kernel API Manual — the whole point is send packet to NIC. no cap, that's literally the name and the vibe.

✨ SYNOPSIS ✨

netdev_tx_t bdx_tx_transmit (struct sk_buff *skb , struct net_device
       *ndev );

🎀 ARGUMENTS 🎀

• skb — packet to send.
• ndev — network device assigned to NIC.

Return codes, bestie:

• NETDEV_TX_OK — everything ok. slay.
• NETDEV_TX_BUSY — Cannot transmit packet, try later. Usually a bug, means queue start/stop flow control is broken in the driver.

Note: the driver must NOT put the skb in its DMA ring. literally do not do that.
