This is a backwards-compatible ABI extension -- we are adding new commands. And I believe OFED has been shipping this ABI for quite a while now (since 1.4?). > I'd like to use this ABI change and introduce/expose also the ib_modify_cq > verb to user space.

OK, but we should coordinate this with all the other ABI extensions that OFED has already made. > One more thing I'd like to add to libibverbs and some device driver > libraries is send-with-invalidate, but this is only user space patch set > without any kernel/user, lib/app ABI change, correct? It is a library ABI change of course to add the send with invalidate opcode. But that is OK. - R. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
