DEV_FORWARD_SKB(9)                    Network device support                   DEV_FORWARD_SKB(9)



NAME
       dev_forward_skb - loopback an skb to another netif

SYNOPSIS
       int dev_forward_skb(struct net_device * dev, struct sk_buff * skb);

ARGUMENTS
       dev
           destination network device

       skb
           buffer to forward

DESCRIPTION
       return values: NET_RX_SUCCESS (no congestion) NET_RX_DROP (packet was dropped, but freed)

       dev_forward_skb can be used for injecting an skb from the start_xmit function of one
       device into the receive queue of another device.

       The receiving device may be in another namespace, so we have to clear all information in
       the skb that could impact namespace isolation.
