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.

net: qualcomm: rmnet: Move common struct definitions to include2019-05-23T16:48:07ZSubash Abhinov Kasiviswanathansubashab@codeaurora.org2019-05-22T20:21:07Zurn:sha1:9395da4efbd46661f0049d24d54d1cea63241fc9
Create if_rmnet.h and move the rmnet MAP packet structs to this
common include file. To account for portablity, add little and
big endian bitfield definitions similar to the ip & tcp headers.
The definitions in the headers can now be re-used by the
upcoming ipa driver series as well as qmi_wwan.
