net: rmnet_data: Add support for MAPv4 data format
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.
