This *could* be a badly configured middlebox attempting to apply a DSCP, but clobbering the entire TOS byte instead of the (left justified) DSCP field. Apparently Comcast just found a whole raft of these in their own network as part of rolling out L4S support. Funny how they didn't notice them previously. - Jonathan Morton _______________________________________________ Bloat mailing list Bloat@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/bloat
