The per-device connection methods proposed by Ammasso are definitely implementable for every iWARP RNIC that I am aware of. It does move some code around from where we have it currently, so we're not ready to release our versions yet. But that's because things take time, not because we think there's anything wrong with the interface. This interface needs to be complemented by the existing IB-specific interface and by an eventual TCP-specific interface that is compatible with the DAT Socket Service Point and/or IT-API's socket convert options. That interface would also deal with interoperability with pre-IETF MPA. But only a handful of applications need those optinons, the DAT-style interface accomodates the vast majority of applications that we are aware of.
