Daniel Borkmann 2da897e51d bpf: fix csum setting for bpf_set_tunnel_key
The fix in 35e2d1152b ("tunnels: Allow IPv6 UDP checksums to be correctly
controlled.") changed behavior for bpf_set_tunnel_key() when in use with
IPv6 and thus uncovered a bug that TUNNEL_CSUM needed to be set but wasn't.
As a result, the stack dropped ingress vxlan IPv6 packets, that have been
sent via eBPF through collect meta data mode due to checksum now being zero.

Since after LCO, we enable IPv4 checksum by default, so make that analogous
and only provide a flag BPF_F_ZERO_CSUM_TX for the user to turn it off in
IPv4 case.

Fixes: 35e2d1152b ("tunnels: Allow IPv6 UDP checksums to be correctly controlled.")
Fixes: c6c3345407 ("bpf: support ipv6 for bpf_skb_{set,get}_tunnel_key")
