The Azure network driver (netvsc) also does not have BQL. Several years ago I tried adding it but it benchmarked worse and there is the added complexity of handling the accelerated networking VF path.
Note that NIC with many TX queues make BQL almost useless, only adding extra overhead. We should probably make BQL something that can be manually turned on/off. _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
