VT: ECN implementation.
[Problem] ecn value needs to be updated but there is no interface
to update the ecn value.
[Solution]
1. Implement interface to set ecn value into socket by
setsockopt(). ecn value will be taking care by upper layer.
2. Configured rx socket to get TOS header then from that extract
ECN bits and based on CE bit handle the bitrate using TMMBR.
