# tcpstates Trace the TCP session state changes with durations.
# For Linux, uses BCC, BPF. Embedded C.
#
# USAGE: tcpstates [-h] [-C] [-S] [interval [count]] [-4 | -6]
#
# This uses the sock:inet_sock_set_state tracepoint, added to Linux 4.16.
# Linux 4.16 also adds more state transitions so that they can be traced.
