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.
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.
