Description

The broker sending link endpoint sends flow performatives when more than half of the credits issued by receiving link endpoint is used. Such behaviour is spec compliant, though, it might effect the messaging throughput as the unnecessary flows consume bandwidth and might impact the performance.

We can simply restrict the sending link endpoint to send flow only in reply to incoming flows with echo= true or drain=true.
