net: rmnet_data: add support for UL MAP based checksum offload
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.
