This driver cannot be built-in if IPV6 is a loadable module:

x86_64-linux-ld: drivers/net/amt.o: in function `amt_build_mld_gq':
amt.c:(.text+0x2e7d): undefined reference to `ipv6_dev_get_saddr'

Add the idiomatic Kconfig dependency that all such modules
have.

It adds definitions and control plane code for AMT.
this is very similar to udp tunneling interfaces such as gtp, vxlan, etc.
In the next patch, data plane code will be added.

IFB originally depended on NET_CLS_ACT for traffic redirection.
But since v4.5, that may be achieved with NFT_FWD_NETDEV as well.

Commit 05cdf457477d ("microblaze: Remove noMMU code") removes config
MICROBLAZE_64K_PAGES in arch/microblaze/Kconfig. However, there is still
a reference to MICROBLAZE_64K_PAGES in the config VMXNET3 in
./drivers/net/Kconfig.

Remove this obsolete reference to config MICROBLAZE_64K_PAGES.

The MBIM protocol has now been integrated in a proper WWAN driver. We
can then revert back to a simpler driver for mhi_net, which is used
for raw IP or QMAP protocol (via rmnet link).

- Remove protocol management
- Remove WWAN framework usage (only valid for mbim)
- Remove net/mhi directory for simpler mhi_net.c file

There are very few ISA drivers left that rely on the static probing from
drivers/net/Space.o. Make them all select a new CONFIG_NETDEV_LEGACY_INIT
symbol, and drop the entire probe logic when that is disabled.

The 9 drivers that are called from Space.c are the same set that
calls netdev_boot_setup_check().

There is not strong reason to have both WWAN and WWAN_CORE symbols,
Let's build the WWAN core framework when WWAN is selected, in the
same way as for other subsystems.

This fixes issue with mhi_net selecting WWAN_CORE without WWAN and
reported by kernel test robot:

Kconfig warnings: (for reference only)
   WARNING: unmet direct dependencies detected for WWAN_CORE
   Depends on NETDEVICES && WWAN
   Selected by
   - MHI_NET && NETDEVICES && NET_CORE && MHI_BUS

Register wwan_ops for link management via wwan rtnetlink. This is
only basic support for now, since we only support creating one
single link (link-0), but is useful to validate new wwan rtnetlink
interface.

For backward compatibity support, we still register a default netdev
at probe time, except if 'create_default_iface' module parameter is
set to false.

This has been tested with iproute2 and mbimcli:
$ ip link add dev wwan0-0 parentdev-name wwan0 type wwan linkid 0
$ mbimcli -p -d /dev/wwan0p2MBIM --connect apn=free
$ ip link set dev wwan0-0 up
$ ip addr add dev wwan0 ${IP}
$ ip route replace default via ${IP}
$ ping 8.8.8.8
...
