net: qualcomm: rmnet: trailer value is a checksum
The csum_value field in the rmnet_map_dl_csum_trailer structure is a
"real" Internet checksum. It is a 16 bit value, in big endian format,
which represents an inverted ones' complement sum over pairs of bytes.
Make that clear by changing its type to __sum16.
This makes a typecast in rmnet_map_ipv4_dl_csum_trailer() and
another in rmnet_map_ipv6_dl_csum_trailer() unnecessary.

net: ethernet: rmnet: Support for ingress MAPv5 checksum offload
Adding support for processing of MAPv5 downlink packets.
It involves parsing the Mapv5 packet and checking the csum header
to know whether the hardware has validated the checksum and is
valid or not.
Based on the checksum valid bit the corresponding stats are
incremented and skb->ip_summed is marked either CHECKSUM_UNNECESSARY
or left as CHEKSUM_NONE to let network stack revalidate the checksum
and update the respective snmp stats.
Current MAPV1 header has been modified, the reserved field in the
Mapv1 header is now used for next header indication.

net: qualcomm: rmnet: don't use C bit-fields in rmnet checksum header
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.

net: qualcomm: rmnet: use masks instead of C bit-fields
The actual layout of bits defined in C bit-fields (e.g. int foo : 3)
is implementation-defined. Structures defined in <linux/if_rmnet.h>
address this by specifying all bit-fields twice, to cover two
possible layouts.
I think this pattern is repetitive and noisy, and I find the whole
notion of compiler "bitfield endianness" to be non-intuitive.
Stop using C bit-fields for the command/data flag and the pad length
fields in the rmnet_map structure, and define a single-byte flags
field instead. Define a mask for the single-bit "command" flag,
and another mask for the encoded pad length. The content of both
fields can be accessed using a simple bitwise AND operation.

net: qualcomm: rmnet: mark trailer field endianness
The fields in the checksum trailer structure used for QMAP protocol
RX packets are all big-endian format, so define them that way.
It turns out these fields are never actually used by the RMNet code.
The start offset is always assumed to be zero, and the length is
taken from the other packet headers. So making these fields
explicitly big endian has no effect on the behavior of the code.

net: qualcomm: rmnet: Fix incorrect UL checksum offload logic
The udp_ip4_ind bit is set only for IPv4 UDP non-fragmented packets
so that the hardware can flip the checksum to 0xFFFF if the computed
checksum is 0 per RFC768.
However, this bit had to be set for IPv6 UDP non fragmented packets
as well per hardware requirements. Otherwise, IPv6 UDP packets
with computed checksum as 0 were transmitted by hardware and were
dropped in the network.
In addition to setting this bit for IPv6 UDP, the field is also
appropriately renamed to udp_ind as part of this change.
