Subject: [PATCH bpf-next 0/2] update skb->protocol in bpf_skb_net_grow

From: Willem de Bruijn <willemb@...gle.com>

Expand the tc tunnel encap support with protocols that convert the
network layer protocol, such as 6in4. This is analogous to existing
support in bpf_skb_proto_6_to_4.

Patch 1 implements the straightforward logic
Patch 2 tests it with a 6in4 tunnel

Willem de Bruijn (2):
  bpf: update skb->protocol in bpf_skb_net_grow
  selftests/bpf: expand test_tc_tunnel with SIT encap
