Because we pass l3proto instead, which is parsed from parse_transport()
And it also returns bpf_redirect().
This is because we will implement the corresponding functions for XDP soon.
To distinguish from XDP lib functions.
Let's copy without any modification.
1. xdp won't be attached to L3 netdev, so no need to handle 0 hlen 2. use xdp bpf helpers instead of skb helpers 3. store metadata in skb->data_meta instead of skb->cb
No adjustment.
This is temporarily needed until AF_XDP forwarding is implemented.
