[Qemu-devel] [PATCH RFC] virtio-net: enable configurable tx queue size

2017-05-18 Thread Wei Wang
This patch enables the virtio-net tx queue size to be configurable between 256 (the default queue size) and 1024 by the user. The queue size specified by the user should be power of 2. Setting the tx queue size to be 1024 requires the guest driver to support the VIRTIO_NET_F_MAX_CHAIN_SIZE
