Subject: [PATCH] net: get stats64 if device if driver is configured
|
||
|
|
|
||
|
|
If the network driver is relying in the net core to do stats allocation,
|
||
|
|
then we want to dev_get_tstats64() instead of netdev_stats_to_stats64(),
|
||
|
|
since there are per-cpu stats that needs to be taken in consideration.
|
||
|
|
|
||
|
|
This will also simplify the drivers in regard to statistics. Once the
|
||
|
|
driver sets NETDEV_PCPU_STAT_TSTATS, it doesn't not need to allocate the
|
||
|
|
stacks, neither it needs to set `.ndo_get_stats64 = dev_get_tstats64`
|
||
|
|
for the generic stats collection function anymore.
