> Yes that makes sense, it's architetural. We can disable ctrl vq though. The problem here is that we know the vring size after calling virtnet_find_vqs, so the number of VQs already includes the control VQ. Actually, many variables/settings that are initialized before we call virtnet_find_vqs may need modifications if we use small vrings. For example has_rss_hash_report, has_rss, hdr_len etc.. We could have a fixup function to fix everything after we discover that we are using small vrings, but, honestly, I think that this will be hard to maintain in the future, and I don't like this approach much. The ideal thing will be to discover if we use small vrings in probe's beginning. I'm looking for a way at the moment. _______________________________________________ Virtualization mailing list Virtualization@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linuxfoundation.org/mailman/listinfo/virtualization
