The motivation for this is based on the observation that although

right, that's what rds does- first reads the sizeof(rds_

Kernel Connection Multiplexor (KCM) is a facility that provides a
message based interface over TCP for generic application protocols.
The motivation for this is based on the observation that although
TCP is byte stream transport protocol with no concept of message
boundaries, a common use case is t
