Introduce 'skb_set_var_tunnel_opt' to allow setting tunnel options of
dynamic length.
v2:
- Place test_tunnel's local route in a custom table, to ensure the IP
isn't considered assigned to a device.
v3:
- Avoid 'inline' for the __bpf_skb_set_tunopt helper function
Shmulik Ladkani (3):
bpf: Support setting variable-length tunnel options
selftests/bpf: Simplify test_tunnel setup for allowing non-local
tunnel traffic
selftests/bpf: Add geneve with bpf_skb_set_var_tunnel_opt test-case to
test_progs
