Replace the use of C bit-fields in the rmnet_map_ul_csum_header structure with a single two-byte (big endian) structure member, and use masks to encode or get values within it. The content of these fields can be accessed using simple bitwise AND and OR operations on the (host byte order) value of the new structure member. Previously rmnet_map_ipv4_ul_csum_header() would update C bit-field values in host byte order, then forcibly fix their byte order using a combination of byte swap operations and types. Instead, just compute the value that needs to go into the new structure member and save it with a simple byte-order conversion. Make similar simplifications in rmnet_map_ipv6_ul_csum_header(). Finally, in rmnet_map_checksum_uplink_packet() a set of assignments zeroes every field in the upload checksum header. Replace that with a single memset() operation.
