TCP TOS not working

jasonstrongman2016:
In 5.3.0 the below works. However, seems to be broken in other
releases. Including this one.

1. /opt/trafficserver60rc3/bin/traffic_ctl -V
   Apache Traffic Server - traffic_ctl - 6.0.0 - (build # 091616 on Sep
   16 2015 at 16:49:13)

1. /opt/trafficserver60rc3/bin/traffic_ctl config match sock_packet_tos_out
   proxy.config.net.sock_packet_tos_out: 184

#tcpdump
