This provides a way to set the traffic class/QoS level for all traffic in the same connection to be the same as the incoming SYN. It could be useful for datacenters to provide equivalent QoS according to the incoming request. This feature is guarded by /proc/sys/net/ipv4/tcp_reflect_tos, and is by default turned off. ==================== Signed-off-by: David S. Miller --- d095c46206be74a96dac2daf21506ab06c3ddfb1
