Gathering interface statistics can be a relatively expensive operation
on certain systems as it requires iterating over all the cpus.
This patch instructs the kernel to not include netdevice statistics, in
the netdevice listing.
Kernel-side support for this was added in Linux v4.4 in commit
d5566fd72ec1 ("rtnetlink: RTEXT_FILTER_SKIP_STATS support to avoid
dumping inet/inet6 stats"); this saves 368 bytes of statistics.
In the Linux v6.19 commit 105bae321862 ("rtnetlink: honor
RTEXT_FILTER_SKIP_STATS in IFLA_STATS"), it is expanded to skip more
statistics, bringing the savings to 800 bytes per netdevice.
