[PATCH v2 0/8] Allow checking SYN cookies from XDP and tc cls act

This series adds the necessary helpers to determine wheter a given (encapsulated) TCP packet belongs to a connection known to the network stack. * bpf_skc_lookup_tcp gives access to request and timewait sockets * bpf_tcp_check_syncookie identifies the final 3WHS ACK when syncookies are enabled
