DIAG
5c2b796e2e
Introduce a flow control context per peripheral and pass this to dm_broadcast() in order for any queued messages to be accounted for in the flow control context. Associate the same flow control context with the read watcher for the peripheral's incoming data descriptors to make the watch runner selectively read from the given peripheral only when the number of outstanding, queued, messages are below the threshold.
