What I did
Added code to hard code the DSCP value to 48 for BFD sessions.
Why I did it
Since BFD is UDP based this would cause its packets to be dropped when congestion is detected in the network. Increasing the DSCP value would give these packets a better chance to make it through.
How I verified it
updated an existing test.
