[PATCH] virtio-net: Reporting traffic queue distribution statistics through ethtool
...es through ethtool -S. The per_cpu
virtnet_stats is split into receive and transmit stats and are
maintained on a per receive_queue and send_queue basis.
virtnet_stats() is modified to aggregate interface level statistics
from per-queue statistics. Sample output below:
NIC statistics:

[RFC PATCH net-next v2 0/2] Enable virtio to act as a backup for a passthru device
This patch series extends virtio_net to take over VF datapath by
simulating a transparent bond without creating any additional netdev.
I understand that there are some comments suggesting an alternate model
that is based on 3 driver model(virtio_net, VF driver, a new driver
virt_bond that acts as a master to virtio_net and VF).
Would like to get some feedback on the right way to solve the live

[PATCH net-next 0/2] Enable virtio to act as a master for a passthru device
This patch series enables virtio to switch over to a VF datapath when a VF
netdev is present with the same MAC address. It allows live migration of a VM
with a direct attached VF without the need to setup a bond/team between a
VF and virtio net device in the guest.
The hypervisor needs to unplug the VF device from the guest on the source
host and reset the MAC filter of the VF to initiate
