[net-next RFC PATCH] virtio_net: collect satistics and export through ethtool
...optimization, so this
patch lets virtio_net driver collect following and export them to userspace
through "ethtool -S":
- number of packets sent/received
- number of bytes sent/received
- number of callbacks for tx/rx
- number of kick for tx/rx
- number of bytes/packets queued for tx
As virtnet_stats were per-cpu, so both per-cpu and gloabl satistics were exposed
like:
NIC statistics:
tx_bytes[0]: 2551
tx_packets[0]: 12
tx_kick[0]: 12
tx_callbacks[0]: 1
tx_queued_packets[0]: 12
tx_queued_bytes[0]: 3055
rx_bytes[0]: 0
rx_packets[0]: 0

[V2 RFC net-next PATCH 1/2] virtio_net: convert the statistics into array
Currently, we store the statistics in the independent fields of virtnet_stats,
this is not scalable when we want to add more counters. As suggested by Michael,
this patch convert it to an array and use the enum as the index to access them.

[PATCH] virtio-net: Reporting traffic queue distribution statistics through ethtool
This patch allows virtio-net driver to report traffic distribution
to inbound/outbound queues 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:
rxq0: rx_packets: 4357802
