Add gro_cells so that rmnet devices can call gro_cells_receive
instead of netif_receive_skb.

Add support to bridge two devices which can send multiplexing and
aggregation (MAP) data. This is done only when the data itself is
not going to be consumed in the stack but is being passed on to a
different endpoint. This is mainly used for testing.

Rather than using a static array, use a hlist to store the muxed
endpoints and use the mux id to query the rmnet_device.
This is useful as usually very few mux ids are used.

The rmnet_devices information is already stored in muxed_ep, so
storing this in rmnet_devices[] again is redundant.

The end point is set twice in the local_ep as well as the mux_id and
the real_dev in the rmnet private structure. Remove the local_ep.
While these elements are equivalent, rmnet_endpoint will be
used only as part of the rmnet_port for muxed scenarios in VND mode.

Make it similar to drivers like ipvlan / macvlan so it is easier to read.

This makes it easier to find out the parent dev.

Data format can be directly set from rmnet_newlink() since the
rmnet real dev info is already available.
Since __rmnet_get_real_dev_info() is no longer used in rmnet_config.c
after removal of those functions, move content to
rmnet_get_real_dev_info().
__rmnet_set_endpoint_config() is collapsed into
rmnet_set_endpoint_config() since only mux_id was being set additionally
within it. Remove an unnecessary mux_id check.
Set the mux_id for the rmnet_dev within rmnet_vnd_newlink() itself.

The current log is not very useful as it does not log the device
name since it it is prior to registration -
(unnamed net_device) (uninitialized): Setting up device
Modify to log after the device registration -
rmnet1: rmnet dev created

rmnet_rtnl_validate() was checking for upto mux_id 254, however the
rmnet_devices devices could hold upto 32 entries only. Fix this by
increasing the size of the rmnet_devices.

RmNet driver provides a transport agnostic MAP (multiplexing and
aggregation protocol) support in embedded module. Module provides
virtual network devices which can be attached to any IP-mode
physical device. This will be used to provide all MAP functionality
on future hardware in a single consistent location.
