I'm looking for the meaning of the node_sockstat_TCP_mem_* metrics. The output of the node exporter describes them as follows:

# HELP node_sockstat_TCP_mem Number of TCP sockets in state mem.
# TYPE node_sockstat_TCP_mem gauge
node_sockstat_TCP_mem 6
# HELP node_sockstat_TCP_mem_bytes Number of TCP sockets in state mem_bytes.
# TYPE node_sockstat_TCP_mem_bytes

The states I know for a socket are like "ESTABLISHED", "LISTEN", "CLOSE_WAIT",... What is this "mem" state ?
