Constant BPF_TCP_ESTABLISHED

pub const BPF_TCP_ESTABLISHED: i32 = 1;

Available on crate feature dep_nc only.

List of TCP states.

There is a build check in net/ipv4/tcp.c to detect changes between the TCP and BPF versions. Ideally this should never happen. If it does, we need to add code to convert them before calling the BPF sock_ops function.
