Hello all:
This seires is an update of last version of multiqueue support to add multiqueue
capability to both tap and virtio-net.
Some kinds of tap backends has (macvatp in linux) or would (tap) support
multiqueue. In such kind of tap backend, each file descriptor of a tap is a
qeueu and ioctls
Sometimes, we need to pass option like -netdev tap,fd=100,fd=101,fd=102 which
can not be properly parsed by qemu_find_opt() because it only returns the first
matched option. So qemu_get_opt_all() were introduced to return an array of
pointers which contains all matched option.
Signed-off-by:
Some operating system ( such as Linux ) supports multiqueue tap, this is done
through attaching multiple sockets to the net device and expose multiple file
descriptors.
This patch let qemu utilizes this kind of backend, and introduces helpter for:
- creating a multiple capable tap device
-
This patch adds the multiqueues support for emulated nics. Each VLANClientState
pairs are now abstract as a queue instead of a nic, and multiple VLANClientState
pointers were stored in the NICState. A queue_index were also introduced to let
the emulated nics know which queue the packet were came
This patch converts the vhost to support multiqueue queues. It implement a 1:1
mapping of vhost devs and tap fds. That it to say, the patch creates and uses
N vhost devs as the backend of the N queues virtio-net deivce.
The main work is to convert the virtqueue index into vhost queue index, this
Based on the multiqueue support for taps and NICState, this patch add the
capability of multiqueue for virtio-net. For userspace virtio-net emulation,
each pair of VLANClientState peers were abstracted as a tx/rx queue. For vhost,
the vhost net devices were created per virtio-net tx/rx queue

I'm not expert of tcp, but looks like the changes are reasonable:
- we can do full-sized TSO check in tcp_tso_should_defer() only for

Hi James,
Please consider picking this one up for your next scsi-rc-fixes PULL,
