I think the point is that only one of those interconnects (IB) is <br>
in the kernel, the rest are proprietary. Do any of the other RDMA<br>

I know some people are working on iWARP devices though this could be done
on the OpenRDMA source work (still a work in progress) which supports
both iWARP and IB.<br><br>
<br>
BTW, I second Tom, et. al. push to use an API to abstract this and avoid
having to permute every subsystem to work for a given device. The
RNIC PI is intended to provide abstraction for iWARP / IB hardware to a
very large extent (think of this as a standard verbs interface). IT
API / DAPL provide another layer of abstraction and can be used to
integrate subsystems either over the RNIC PI or whatever verbs API people
desire.<br><br>
