Re: Comcast Network Peer Survey on DSCP/ECN for L4S

[Jared Mauch <jared () puck nether net>]

This seems to be missing some of the reasons/why things are remarked, perhaps it would be wise to bring some of the 
people interested in this to the various vendor-specific lists or such?

For example, for some hardware types, enabling any sort of rate shaping at all will rewrite the DSCP values, even for 
packets that do not traverse the shaped interfaces.
