[openib-general] OpenIB and OpenRDMA: Convergence on common RDMAAPIs and ULPs for Linux

[Caitlin Bestler]

The current OpenIB structure is, not surprisingly, tremendously
IB-centric. Any attempt to implement an iWARP RNIC through
them will have to go through several layers of obfuscation.

States do not match. Error codes do not match. Completion
Statuses do not match. There is a lot of information that
does not translate to iWARP, and there is information that
is missing.

RNIC-PI is at least an attempt at providing full control over
both iWARP and IB while making as much common as
possible.

I believe it is possible to define a verb set that is largely
compatible with current OpenIB IB verbs and have the
same transport neutrality that RNIC-PI has. But this will
not be just poking around and tweaking one or two 
elements in the OpenIB code.

Is there a real willingness in OpenIB to make a transport
neutral verb layer? Has anyone even *read* the RNIC-PI
for substance rather than "pure Linux" debating points?
