How to set DSCP value on gRPC stream in C++?
The gNMI standard has a qos field that is used to mark the DSCP value of the gRPC stream. Does gRPC C++ API support setting DSCP on the stream? Doing it with setsockopt would require us to get the socket file descriptor...
Based on implementation discussions, we're currently in the process of working on an update that deprecates the qos field in the proto - based on gRPC support. We'll rather prefer a statically configured DSCP for the whole service. Operational experience has shown that there's little benefit of per subscription QoS.
So an implementation has to remark the frames from gRPC externally? Or gRPC will add support for service based DSCP?
