This series from Ariel implements the libibverbs 'Completion timestamping' API in the mlx4 provider. It implements the new iterator style CQ polling API with support of querying specific CQ fields, among them the completion timestamp. Benchmarks we ran in our test lab found that this new approach generally equals to the legacy API but *not* worse than. As the new API enables extending the polled fields we can overall say that it's a better API than the legacy one.
