[PATCH net-next 0/4] netdev: support dumping a single netdev in qstats

[Jakub Kicinski <kuba@kernel.org>]

I was writing a test for page pool which depended on qstats,
and got tired of having to filter dumps in user space.
Add support for dumping stats for a single netdev.

To get there we first need to add full support for extack
in dumps (and fix a dump error handling bug in YNL, sent
separately to the net tree).

Jakub Kicinski (4):
  netdev: support dumping a single netdev in qstats
  netlink: move extack writing helpers
  netlink: support all extack types in dumps
  selftests: drv-net: test dumping qstats per device
