The role of the libibverbs library has been taken over by a new package called rdma-core and hosted on github. A multitude of different RDMA packages were pulled together to make the rdma-core package, and all of the components that went into it are not obsolete. Users should transition to the new rdma-core package to get ongoing development and support. "
