Subject: [PATCH bpf-next v2 0/2] update skb->protocol in bpf_skb_net_grow

From: Willem de Bruijn <>

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

Changes v1->v2
  - improve documentation in test

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