ca32fb034c net: qualcomm: rmnet: Add support for GRO
Add gro_cells so that rmnet devices can call gro_cells_receive
instead of netif_receive_skb.

85355d775f net: qualcomm: rmnet: Always assign rmnet dev in deaggregation path
The rmnet device needs to assigned for all packets in the
deaggregation path based on the mux id, so the check is not needed.

2ffbbf0f91 net: qualcomm: rmnet: Fix the return value of rmnet_rx_handler()
Since packet is always consumed by rmnet_rx_handler(), we always
return RX_HANDLER_CONSUMED. There is no need to pass on this
value through multiple functions.

60d58f971c net: qualcomm: rmnet: Implement bridge mode
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.

3352e6c457 net: qualcomm: rmnet: Convert the muxed endpoint to hlist
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.

56470c927f net: qualcomm: rmnet: Remove duplicate setting of rmnet private info
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.

Mode information on the real device makes it easier to route packets
to rmnet device or bridged device based on the configuration.

ceed73a2cf drivers: net: ethernet: qualcomm: rmnet: Initial implementation
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.
