rmnet_data assigns device name by the order they are created.
This causes problems which multiple processes are trying to
create devices and leads to random device names.
Assign device name as specified by user.

Add the MAPv4 ingress and data format handlers. MAPv4 requires the
checksum for uplink TCP and UDP packets to be 1's complemented
before passing the packet onto the physical netdevice.
This workaround is needed due to failures seen in hardware while
processing translated packets.

Add UL checksum offload routines for MAPv3. Can bypass checksum software
for IPv4/IPv6 TCP/UDP protocols.
Set rmnet_data VNDs hw_flags to NETIF_F_IP_CSUM | NETIF_F_IPV6_CSUM to
define the checksum offload abilities.
Add UL checksum meta-info header for IPv4/IPv6 TCP/UDP packets for which
UL checksum is being offloaded.

Added new parameter tail_spacing to
RMNET_NETLINK_SET_LINK_INGRESS_DATA_FORMAT in order to support
an additional fixed padding on packets. Required to support RNDIS
tethering.

Implement MAP based in-band flow control. Added 2 new configuration
messages to allow adding and deleting flow handles. Added handlers
in VND for flow control events. Added flow control command handler
in rmnet_map_commands.

Run-time user space components can now specify virtual network device
name prefix at device creation. This will be used to support legacy
data services.

RmNet Data driver provides a transport agnostic MAP (multiplexing and
aggregation protocol) support in embedded and bridge modes. 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.
