Subject: [PATCH net-next v2 0/2] net: store netdevs in an xarray

One of more annoying developer experience gaps we have in netlink
is iterating over netdevs. It's painful. Add an xarray to make
it trivial.

v2:
 - fix the potential mishandling of wrapping (Leon)
v1: https://lore.kernel.org/all/20230722014237.4078962-1-kuba@kernel.org/

Jakub Kicinski (2):
  net: store netdevs in an xarray
  net: convert some netlink netdev iterators to depend on the xarray
