Can you expand on this comment to describe what it means. I looked up Neagle's
algorithm and I'm not entirely sure why "no delay" is an appropriate description
of it.

I extended comments for this option in ppb_transport_dev.h. It is conventionally
called 'no delay' (TCP_NODELAY to be exact) in other TCP implementations, e.g.
see "man 7 tcp" (http://en.wikipedia.org/wiki/Nagle's_algorithm also mentions
it)

+    bool tcp_no_delay;
+
+    // TCP ACK delay.
+    int tcp_ack_delay_ms;
