>From Moni,
Following the discussion [1] on the mailing list regarding
"Custom/proprietary QP type support", the following patchset
implements the direct connected QP types functionality over posted RFC.
The dynamically connected (DC) transport service provides a datagram-like
model that allows a DC QP to target multiple remote processes in multiple
remote nodes.
As far as reachability is concerned, the DC model is somewhat similar to
the unreliable datagram (UD) model in the sense that each WR submitted to
the DC SQ carries the information that identifies the remote destination.
The new QP type - IB_QPT_DRIVER is introduced to represent all type of QPs
that are driver specific, like the proposed DC QP. Such minimal change
to the IB/core allows reuse of existing verbs functions to control those
new QPs with already existing functions.
