[RFC] [ver3 PATCH 0/6] Implement multiqueue virtio-net
This patch series resurrects the earlier multiple TX/RX queues
functionality for virtio_net, and addresses the issues pointed
out. It also includes an API to share irq's, f.e. amongst the
TX vqs.
I plan to run TCP/UDP STREAM and RR tests for local->host and
local->remote, and send the results in the next couple of days.

[PATCH 0/6] vDPA: doorbell mapping
Hi all:
This series introduce basic functionality of doorbell mapping support
for vhost-vDPA. Userspace program may use mmap() to map a the doorbell
of a specific virtqueue into its address space. This is help to reudce
the syscall or vmexit overhead.
A new vdpa_config_ops was introduced to report the location of the
doorbell, vhost_vdpa may then choose to map the doorbell when:
