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
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
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.

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
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

Please review.
Thanks.
v4:
1. Support per-queue statistics API
2. Fix some small problems in last version
v3:
1. rebase net-next
v2:
