This series improves the CPU cost of RX token management by adding an
attribute to NETDEV_CMD_BIND_RX that configures sockets using the
binding to avoid the xarray allocator and instead use a per-binding niov
array and a uref field in niov.

I see that net_devmem_dmabuf_binding_get() is lacking a
stub for CONFIG_NET_DEVMEM=n ...

Just curious how pw works... is this a randconfig catch? I ask because
all of the build targets pass for this series (build_allmodconfig_warn,
build_clang, etc.. locally and on patchwork.kernel.org), and if there is
a config that pw uses that I'm missing in my local checks I'd like to
add it.

kunit hit it on our end
