Something like: SEND, RECV, INIT READ, INIT WRITE, READ TARGET, WRITE TARGET, etc. We're close to > this, but it's not clear, for example, what flags are needed for a receive buffer. None? LOCAL_WRITE? Make sense to me too. To stage the changes we could introduce a new function that returns the needed ib_access_flags value given the desired opcodes. Then have a series that changes all the existing ULPs to make use of this new function.
