Description
Hi,
It seems the -tos option is not working. I built the lastest release using the Dockerfile provided in the code and ran a client and server container based on centos 7. When inspecting the packets from the client, the ToS field in the IP header was not set.
I ran the server and client as following:
Dockerfile to test:
FROM centos:7
COPY ethr /
Server:
docker run --rm --name server ethr-test ./ethr -s
Client:
docker run --rm --name client ethr-test ./ethr -c 172.17.0.2 -b 10M -p tcp -t b -tos 56
I inspected the packets in the docker0 interface using Wireshark and this is how they looked:
I tried different values for ToS but none of them worked.

Research direction
Reproduce the report using the provided Dockerfile and the server and client commands, then inspect traffic on the docker0 interface. Start at the ./ethr entry point and trace how -tos 56 is handled; done means the requested value appears in the IP header for the generated traffic.
