net-next is closed. Please resubmit next week.
As the spec:
https://github.com/oasis-tcs/virtio-spec/commit/42f389989823039724f95bbbd243291ab0064f82
The virtio net supports to get device stats.
Please review.
Thanks.
v5:
1. Fix some small problems in last version
2. Not report stats that will be reported by netlink
3. remove "_
To enhance functionality, we now support reporting statistics through
the netdev-generic netlink (netdev-genl) queue stats interface. However,
this does not extend to all statistics, so a new field, qstat_offset,
has been introduced. This field determines which statistics should be
reported via net
In the last commit, we use the stats map to manage the device stats.
Managing driver statistics separately can be inconvenient. To streamline
the process, I propose integrating driver stats into the existing stats
map. This integration will allow us to uniformly handle all statistics
through a sin
Now, we just show the stats of every queue.
But for the user, the total values of every stat may are valuable.
NIC statistics:
rx_packets: 373522
rx_bytes: 85919736
rx_drops: 0
rx_xdp_packets: 0
rx_xdp_tx: 0
rx_xdp_redirects: 0
rx_xdp_drops: 0
rx_kicks: 111
These stats are commonly. Support reporting those via netdev-genl queue
stats.
name: rx-hw-drops
name: rx-hw-drop-overruns
name: rx-csum-unnecessary
name: rx-csum-none
name: rx-csum-bad
name: rx-hw-gro-packets
name: rx-hw-gro-bytes
name: rx-hw-gro-wire-packets
name: rx-hw-gro-wire-bytes
name: rx-h
As the spec
https://github.com/oasis-tcs/virtio-spec/commit/42f389989823039724f95bbbd243291ab0064f82
make virtio-net support getting the stats from the device by ethtool -S
.
Due to the numerous descriptors stats, an organization method is
required. For this purpose, I have introduced the "virtn
The key size of ethtool -S is controlled by this macro.
ETH_GSTRING_LEN 32
That includes the \0 at the end. So the max length of the key name must
is 31. But the length of the prefix "rx_queue_0_" is 11. If the queue
num is larger than 10, the length of the prefix is 12. So the
key name max is 19
Now, we have this:
tx_queue_0_tx_timeouts
This is used to record the tx schedule timeout.
But this has two "tx". I think the below is enough.
tx_queue_0_timeouts
So I rename this field.
