using a ctrld proxy container for DNS requests. when enabling doq , it complains about buffer size which seems to be derived from underlying OS(routerOS):
As stated here you can mute this message with environment variable QUIC_GO_DISABLE_RECEIVE_BUFFER_WARNING with value set to true. AFAIK you cannot change kernel TCP window / UDP buffer size in ROS.
That is obvious, but it seems they are not willing to expose such parameters as ROS configuration, probably to avoid possibility for making system unstable by user config.
